1939 World's Fair souvenir

My best friend popped by with this dandy trinket he found in a box of his mother''s things. It's a small (about 1x2 inch) steel replica of one of the exhibits at the 1939 New York fair.."The World's Largest Typewriter" by Underwood. Despite this geegaw's small size, it apparently was designed to be a bank. You might be able to stick 5 dimes in it.

Sorry about the fuzzy macro-shot..wanted to show the Trylon and Perisphere on the back.
