This post is titled very carefully as I know not everybody considers rookie year items that aren't Topps or Bowman to be actual rookie cards. I am more lenient in my definition of rookie and fully consider today's Dandy Sandy score to be a full-fledged rookie card.
I really love the 1955 Golden Stamps set. A number of different teams are featured; you can buy them already removed from the book or buy a full and complete book; and the Dodgers' offering features Campy, Jackie, Hodges, Snider, Podres, and a host of other great and memorable players.
