I've been "playing" with my 1974 Parker Brothers football cards this morning. I re-discovered that not only were six cards printed with new fronts (three horizontal cards like this Norm Snead, and three ALL-PRO cards), these six cards also got a later printing using the new photos. In this example using Norm Snead, the top card is his regular Topps card printed horizontally. The middle card is the standard Parker Brothers card with the new pose and 1972 stats (also the two asterisks we look for ** @ T.C.G. PRTD. IN U.S.A.). The third card has the new pose but the back has 1973 stats and a single asterisk (* @ T.C.G. PRTD. IN U.S.A.)
