Featured above is a fantastic AP press/publicity photograph that features Jackie Robinson in the midst of being tackled by two college gridiron all-stars. (eBay Auction Link) This photo was taken on August 15, 1949 at a BBWAA get-together in Bear Mountain, NY. Per the descriptor on the reverse:
Note that Jackie, a guest at the outing, is wearing a slipper on his left foot injured in a recent game.
