I picked up a couple cards from the same vendor as the other free signers. They're decent enough cards to get signed. Lilly was the last free signer that I needed, which will move me on to posting some other stuff.
Lilly (b. 1939) played professionally from 1961 to 1974 for the Cowboys. He was an 11-time pro bowler and was elected to the Pro Football Hall of Fame in 1980. He won Super Bowl VI with the Cowboys.
Lilly was really nice. His line moved super slowly, but he took his time to sign and talk with everyone.
