when we visited MOMA while in New York my husbandwas horrified to see me pick up the maps in every single language they had. they looked so pretty in rainbow order that i couldn't resist them.
there is no problem with taking pictures in the gallery so this is one of my husband walking on one of the pieces of art. He gets really annoyed about art like this, paving slabs on the gallery floor. so when he saw the sign "please feel free to walk on the art work" he was only to happy to oblige
