Vintage foobtall player photo identification
 

Hi-
I posted this on the autograph forum about a week ago and someone thought the last name might end in a K but I still could not identify the player.

I recently acquired the football photo scanned below and I was wondering if anyone could help with the signature. Any idea who it is? What team he played for? My best guesses were Jerry Thule or Jimmy Thule but I have had no luck with google. The back of the photo has some calculations on it but no identification information. I realize this could just be a local college player but I figured I would give it a shot. It was purchased from an ephemera dealer who mostly buys in Pennsylvania.
Thanks in advance,
