Here is one I haven't seen posted yet. This is one of my favorite autos in my HOF collection, as this is his only pack-issued autograph card and I bought it in the hospital room when my son had just been born (he and my wife were asleep, which I feel the need to point out so it doesn't seem that I was surfing ebay instead of binding with my newborn!).
Also a bit of trivia- Day is the only player whose cap in the HOF is a Puerto Rican team (Aguadilla Sharks)
