That tobacco album is amazing!
My pick is one that I don't see often (in a safe deposit box), but this ball has got to be the most satisfying piece I own. It was taken by my dad to many an Enid Giants class C game, as he collected sigs of his hometown players, but his prize target was always Mantle. He got this signed the year the 18 year old then shortstop hit .383.

And for good measure, my dad a few years later, playing for the Enid "Little Giants". I'd never seen this pic of him until 2 weeks ago.
