There was a vendor right near the bathrooms at the show who had a display board with cards of most of the free signers for $5.00/card. Some (most) of those were a gross overpay, but in the end, my time was valuable, and it saved me from spending hours at dime boxes looking for random folks. So, I purchased a few of the guy's cards, like these of Mike Nelms. The card above is a 1983 Topps.
Nelms (b. 1955) played in the NFL from 1980 to 1984 for the Redskins. He was a 3-time Pro Bowler (1980, 1981 and 1982) and an All Pro in 1983. He won the Super Bowl with the Redskins in 1983 (1982 season) when the Redskins defeated the Dolphins.
