In 1926 the Mack Studio in Pottsville, Pennsylvania produced a series of real photo post cards of members of the Pottsville Maroon NFL football team. Some would consider this is the first set of cards for professional football.
Pictured above is Frank Racis, a member of the Pottsville squad from 1925 to 1928. He and my father were teammates on the 1928 Pottsville squad which ended its season on November 29 with a loss to the Providence Steam Roller. Then my father went to the NY Giants and Racis went to the NY Yankees and they played against each other on December 16th at Yankee Stadium. They met on the field a number of times in the following years as my father stayed with the Giants and Racis went to the Boston Bulldogs in 1929, the Providence Steam Rollers in 1930, and the Frankford Yellow Jackets in 1931. Although the postcard has a notation that Racis went to Yale, the official NFL records list no college.
