The 1951 Bowman set of 144 numbered cards witnessed an increase in card size from previous Bowman football sets. Cards were issued in six-card nickel packs and one-card penny packs. The cards were enlarged from the previous year to 2 1/16" by 3 1/8". The set is very similar in format to the baseball card set of that year. The fronts feature black and white photos that were colored in. The player's name is in a bar toward the bottom that runs from the right border toward the middle of the photo. A team logo or mascot is on top of the bar. The card backs are printed in maroon and blue on gray card stock and contain a write-up. The set features the Rookie Cards of Tom Landry, Emlen Tunnell, and Norm Van Brocklin. The Bill Walsh in this set went to Notre Dame and is not the Bill Walsh who coached the San Francisco 49ers in the 1980s. The set numbering is arranged so that two, three, or four players from the same team are together. Three blank backed proof cards have recently been uncovered and added to the listings below. The proofs are very similar to the corresponding base card. However, the artwork varies somewhat versus the base card.
