Found object: 1959 USSR Exhibition pin

This pin is a rectangle that is roughly 1" x .5". It commemorates the 1959 exhibition made by the USSR in New York City in June and July. I found this on the sidewalk while out taking a walk one day in a modest sized city in Central Illinois perhaps 10-15 years ago. It is one of the more odd, out of place things that I have found and I have found many objects while taking walks. It is in pretty good shape, so was probably not lying there for long before I happened upon it.
