Vintage football autograph help "Labe" Safro

GR

Recently at auction a collection of boxing autographed photos all belonging to former boxer Big Ben Moroz were auctioned, The box went for way too much for me to compete, however after negotiation I was able to buy an 8x10 Cabinet photo signed and personalized by Former Pro Football player "Labe" Safro. Its a Sussman photo from Minneapolis and features him in his boxing gear and labeled Worlds champion bag puncher. The signature is dated 10-30-44. He played for the Mineapolis Marines prior to entering into the NFL. If anybody can help me assess its potential value id appreciate it! (: Thanks
