Preserving ‘Herblock’ a Rewarding Job for Conservators

Ever wonder what goes on before an exhibition is mounted and displayed?  My colleague Donna Urschel takes an in-depth look at the preservation steps that were required for the Library’s “Herblock!” exhibition, on display through May 1:

Preserving ‘Herblock’ a Rewarding Job for Conservators

by Donna Urschel

Shortly after the famous Washing­ton Post political cartoonist Herb Block (“Herblock”) died in late 2001, Holly Krueger was part of a small reconnais­sance party checking out the condition of the cartoons in Block’s Georgetown row-house basement.

Krueger, a senior paper conservator in the Conservation Division in the Library’s Preservation Directorate, took a small elevator down to Herblock’s non-finished basement and walked to the back, where there was a small, secured room.

Inside, Krueger found metal cabinets stuffed with cartoons, tables stacked with cartoons and boxes filled with cartoons— 14,400 in all. A moldy carpet covered the floor. Miraculously, there was no mold on the cartoons.

Krueger was accompanied by Harry Katz, a curator at the time in the Library’s Prints and Photographs Division, and members of the Herb Block Foundation—which had donated Herblock’s entire col­lection to the Library of Congress along with funds necessary for its preservation. They all agreed on the next step: remove the cartoons as soon as possible. Within a week, the Library sent a team to pack up the drawings and bring them to the Library.

“When I first stepped into the room, my first reaction was just of awe. I was standing amidst the entire life work of an incredible 20th-century figure,” said Krueger. “My second thought was ‘Boy, are we lucky they’re in good condition.’ And then I felt anxiety, an anxiety shared by the trustees to get the cartoons out as quickly as possible.”

Krueger has been the lead conservator in preserving the collection of Herblock, the master of political cartooning. For more than 70 years, from 1929 to 2001, he crusaded against corruption and injustice, inequality and immorality. He was a four-time winner of the Pulitzer Prize.

Herblock’s work is on display at the Library in an exhibition that celebrates his long career. The exhibition–which opened on the 100th anniversary of his birth, Oct. 13, 2009–is located in the second-floor South Gallery of the Thomas Jefferson Building and runs through Sat­urday, May 1.

On Wednesday, Feb. 10, Krueger will hold a noontime gallery talk in the exhibi­tion area to discuss the Library’s efforts to preserve Herblock’s voluminous body of work.

Fortunately, with the supplemental funds from the Herb Block Foundation, Krueger and her conservation team were able to prepare the collection for service. But there were many challenges along the way.

The majority of the drawings were executed in graphite media pencil, a substance that is very “friable,” which means the pencil smudges and rubs off easily. Each drawing had a clear sheet of tracing paper stapled on top to prevent smudging.

“But the translucent paper was of poor quality, so we knew it had to be replaced. And we knew each drawing would need individual housing,” Krueger said. “We had to develop a housing that was stiff enough to keep the cartoon from flexing and find a good, translucent paper that would prevent smudging.”

Krueger continued, “It was a chal­lenge to design housing to accommodate safety needs, yet provide easy access to the drawing and fit in the allotted space in the Prints and Photographs Division.” Once the conservation team designed the housing system, the Library com­missioned an archival supply company to make the product.

Krueger’s team also had to deal with the treatment needs of some of the draw­ings, including tear repair, tape removal and consolidation. Some of the materials used did not adhere to each other very well, such as the Wite-Out™ and the stick-on labels. Each of these elements had to be re-adhered to the drawings using a variety of appropriate adhesives.

Now all 14,400 cartoons have been properly treated and housed in their own individual folders, a project that took five years. The project also included dealing with Herblock’s 50,000 “roughs,” pre­liminary cartoons drawn on poor-quality newsprint. Some had been housed in Herblock’s Georgetown basement with the finished drawings, but most were stored in a warehouse.

“He saved everything!” said Krue­ger.

Each day, when Herblock was trying to decide what cartoon to draw, he would sketch up several possibilities. Then he would take these rough drawings around to his colleagues at the Washington Post and ask their opinions.

The roughs have been sorted and placed into archival file folders by the Library’s conservation team. The rough drawings are not available to the public, because they are in poor condition and cannot be handled. “We would like to digitize them,” said Krueger. “There’s a gold mine in there, depictions of his thought process that haven’t been seen before.”

The next preservation phase for the Herblock col­lection involves further study of the materials he had used. “Launching into this new study will be very satisfying for me. I hadn’t had a chance to catch my breath. But now I can go back and take a more in-depth look at the cartoons from a materials standpoint,” added Krueger.

The results of this study will help the Library store the cartoons under the best possible condi­tions in the future and guide conserva­tors on how best to handle the drawings during exhibitions.

Krueger also is working with Fenella France from the Library’s Preservation, Research and Testing Division in moni­toring the Herblock cartoons while on display in the current exhibition. Seven drawings underwent hyperspectral imag­ing prior to display, to get a baseline on their condition. They will continue to be examined via hyperspectral imag­ing three months into the exhibit and again at the end. The results will show if or how the cartoons changed during exhibition.

“It’s been a huge privilege to work on this collection,” Krueger said. “I’ve been able to closely observe the work of a really great artist, watch the development of his style. It’s been humbling to see his body of work. He had a lot of integrity, knew what he believed in and fought for it. And I’ve learned a lot about the 20th century.”

The preservation stories of Krueger and other conservators and scientists in the Preservation Directorate will be shared with the public starting some­time this spring, when Preservation rede­signs its web pages. Staff members will write first-hand accounts of their experi­ences handling the Library’s treasures. The launch of the web pages will be announced later.

  1. I know the name “Herblock” but I am not familiar with his work. Political cartoons have never really interested me but reading about the work done to preserve these images has sparked my interest. I hope to come and see the exhibit when I am in town.

  2. Interesting but I wouldn’t call this an “in-depth look at the preservation steps.” This was very short on real info about preservation techniques!

  3. Thanks for taking us “behind the scenes.” I’m a library science student and I read that it took 5 years to complete this project. Just curious as to the average length of time it takes to preserve a collection. I’m sure it has a lot to do with the amount and condition of the items, but I wonder are there other factors involved as well that could expedite or delay the process.

  4. Please add the details of what papers were selected for the folders, the cover sheet, etc.

  5. It is a great please to see all the body of work completed, on display and the great book. I enjoyed a lot working closely with Holly Kruger, Sara Duke and the staff from the Prints and Drawing Division. Overall, it was a lot of work preparing (approximately 500 cartoons per week over 2 years) and gratification to see the end of the project.

  6. It is a pleasure to see all the body of work completed, currently on display and the great book about Herblock Collection. I enjoyed a lot working closely with Holly Krueger, Sara Duke, Martha Kennedy and all the staff members from the Prints and Photographs Division at the Library of Congress. Overall, it was a lot of work preparing and stabilizing this collection (approximately 500 cartoons per week over 2 years). Also, it was a wonderful gratification to see the end of the project and read about the results now.

  9. Actually, I’m not really familiar with his work, though indeed I never heard the name “Herblock.” Actually I am interested in political cartoons, I hope to see the high imagination work.

  10. This was very short on real info about preservation techniques!
