Except for some of the specialty cards, Topps returned to a vertical format with their 1961 cards. The set is numbered through 598, however only 587 cards were printed. No numbers 426, 587 and 588 were issued. Two cards numbered 463 exist (one a Braves team card and one a player card of Jack Fisher). Actually, the Braves team card is checklisted as #426. Designs for 1961 are basically large color portraits; the backs return to extensive statistics. A three-panel cartoon highlighting the player's career appears on the card backs. Innovations include numbered checklists, cards for statistical leaders, and 10 "Baseball Thrills" cards. The scarce high numbers are card numbers 523-589. - 2006 Standard Catalog of Baseball Cards, 15th Edition.
