Measuring 3-1/8" x 5-1/4" the Topps Giants were the company's first postcard-size issue. The cards feature large color photographs surrounded by white borders with a white baseball containing the player's name, position and team. Card backs carry another photo of the player surrounded by a newspaper-style explanation of the depicted career highlight. The 60-card set contains primarily stars which means it's an excellent place to find inexpensive cards of Hall of Famers. The '64 Giants were not printed in equal quantity and seven cards, including Sandy Koufax and Willie Mays, are significantly scarcer than the remainder of the set. - 2006 Standard Catalog of Baseball Cards, 15th Edition.
