This set consists of 13 numbered panels (plus seven variations). Each pictures three athletes, including one, two or three baseball players; the others include football stars, golfers, skaters, racers, etc. The entire panel measures approximately 8-1/4" X 6" - while the card, if cut out, measures 6" square. Each athlete is pictured in what looks like a postage stamp with a serrated edge. A brief biography appears alongside the "stamp". Billy Herman is pictured on this example cut from an original panel and graded NM-MT (ST) by PSA.
