Sendak's Childhood Visit to the 1939-1940 New York World's Fair

At the Walt Disney Family Museum, we currently have an exhibit about author and illustrator Maurice Sendak. I thought this timeline in the exhibit was a good demonstration of power of world's fairs on younger visitors. I'm going to see what else I can find about his childhood visit to the 1939-1940 New York World's Fair, but it was clearly important enough for the exhibit planners to include it in his timeline.
