Why were we all taking pictures of the art work? Maybe it jogs our memories, but I know I quickly deleted most of them. Next time I visit an art museum, I'm putting away my camera and concentrating on the art.
Or look first and then go back and take a shot of the ones which you found to be most powerful. (That is if you are allowed. Some museums have strict rules for photography.) This is a good shot though- really captures a generation and how they see life.
