When I ran across this image recently, it struck me just how much parades and flags go together and, furthermore, how much people have experimented with displaying enormous flags. In this case, the flag was probably better seen from the photographer’s vantage point than by spectators on the ground.

As is so often the case, one picture led to another, and I found myself tracing Flag Day, celebrated in the U.S. every June 14th, through pictures.
