Identification of cards

Vaultdweller

So my Uncle Marv posted this picture of the four cards he has from his career. Can y'all identify them for me so I can try and get more? Are there any other cards of him out there?

Does anyone have any memories of him or anything? He was a huge star for USC, but his pro career was cut short due to injury. I'd love to pass along some stuff for him.

The top left and bottom right were not issued during his playing days. He only had 3 cards issued during his playing days and you have 2 of them there.

Bottom left: 1972 Sunoco stamp
Top right: 1974 Topps
