First, Keith Olbermann's collection. The Collins proof, all the other un-issued proofs, a couple Wagners.
Second, Richard Masson (sp?). He has a near set of T215 Pirates, a large number of T215 Red Cross, and who knows what else.
Third, David Hall. He's going for a T206 Master set. I would love to see them, even the cards he's outbid me for.
