I found this today at an antique store.  It’s the old blue and gold, Sullivan High Pirates.  Looks like a booster item to be.  I can’t even hazard a guess as to the date.  I went there 1961-1963 and don’t recall ever seeing one.  But, then, I never paid much attention to sports.

It’s 1.25″ in diameter with a lethal-looking pin on the back.  Those were dangerous times…
