I've long tried to add Dave's Orioles Crown card to my collection since it's the only card that pictures him with the Orioles, but things never quite worked out. Dave would sign some TTM requests for other collectors, but mine always went unanswered.
Originally, I had a signed Reds card of his in my collection, and eventually acquired a signed Rochester Red Wings card, which was a half-step upgrade since it was at least an Orioles organizational card, but the autographed Crown card continued to elude me.
Until I was able to work out a trade with fellow Orioles collector, Billy, who has also written an Orioles autograph blog, Billy's Orioles Collection. He very kindly left a hole in his collection by trading away his signed Van Gorder Crown card, which Dave had signed TTM for him, but I knocked out a number of people on Billy's need list to make up my end of the deal, including the Van Gorder Red Wings card, so at least he still has a signature of Dave's.
Thank you so much Billy, I really, REALLY, appreciate the trade.
