My latest acquisition

I know it's not a pinback or a button, but this is way cool to me. I got two of them. Unfortunately, they aren't as in good condition as they look in the picture (discoloration, a hole or two), but I gotta figure they are probably from when he (Spark Matsunaga) first ran for Senate -- and that would be 1976. They just don't make campaign propaganda like they used to! And, not bad for 30 years old, I suppose.
