1973 Willie Mays - The first card of my idol in the uniform of my beloved Mets.
1978 Reggie Jackson - The classic Reg-gie follow through. Awesome!!
1972 Willie McCovey - Love the blurry hand. Can't recall another Topps card with that effect.
1962 Roger Maris - As a kid I heard of Maris' accomplishment like it was ancient history. Had one of these cards with a hole punch in it squirreled away in my collection.
1974 Nolan Ryan - This one needs no explanation. Look at that shot!!
1976 Johnny Bench - In a word, "intimidation."
1977 Dave Kingman - My absolute favorite player in a great photo.
1958 Mantle/Aaron - I wish the Mick was looking straight ahead, but that's just splitting hairs.
1965 Casey Stengel - Sitting on a bench and gesticulating. What's not to love?!
1972 Bobby Bonds - Look at that grin on his face. It says, "I can't believe I didn't launch that pitch!!"
