In 1998 Ron Mix released a series of signed cards. All living Hall-of-Famers except one signed these cards. I believe the one living Hall-of-Famer that did not sign was John Riggins. Fortunately, John Riggins loosened up in later years and there is a lot of signed Riggins stuff out there now.
I believe these cards were sold to benefit retired football players. Below are all the Redskins football cards in the set. I have included Paul Krause even though the Hall-of-Fame does not list him as a Redskins HOF’er.
This is a well designed set and you can tell that a lot of thought and care were put into it.
