The hobby of collecting baseball cards picked up steam in the early 1950s, when athletes such as Mickey Mantle, Hank Aaron, Willie Mays and Sandy Koufax graced the baseball diamond. The sport was embraced as the national pastime, and boys were in heaven trading and coveting the cards of their favorite players. Each has a unique story of how and when it was obtained, its significance to the owner, and the question of how the collection will be passed onto future generations.
