1948 Bowman...they are postcards that were put out by SMU (they are postmarked on back 1951 but were likely made before that as Walker had already graduated by 1951). These are the first I have seen but I'm sure there are more out there. They are (obviously) signed on the front by the players, they were likely used to answer autograph requests.
I agree they are among my favorite football cards of the period.
