Here are the pics. The back letters are 3 inches, and the "A" on the front is 3.5 inches. Just looks very small. Would make sense if they were doing the about same size letters back then but from some of the gameworn pics I've seen they look quite a bit larger.
I'm try to find a way to post the one or two Im talking about but here is mine for now.
