I think the idea of the World's Fair is a cool idea. I wish I had been around for the early ones. They look so fun! I am obsessed with the 1933 and 1939 World's Fairs.
This rug commemorated the 1933-1934 World's Fair in Chicago. Entitled "A Century of Progress", it focused on science.
I used to own this cool rug, but had to sell it a few years ago. Gotta eat, you know. It went for $50. I found out recently that it was worth a few hundred dollars. Total bummer!
