In Orioles autograph lore, Drungo had retained the title of being one of the toughest autographs to track down for many years until Chris Potter, a local autograph signing facilitator, tracked him down for a signing late last year. I have no idea if Chris knew that Drungo was sick and fighting the effects of cancer, but it will likely remain the only large-scale signing that Drungo ever did in his lifetime. The Bee article touches on this, but it seems like Drungo just didn't know why or how so many people wanted his autograph since his MLB career lasted all of 6 games, so he didn't sign TTM and remained obscure enough to stay off the radar of many larger autograph promoters.
I've written about my experiences with tracking down his autograph a few times (here and here), as it was quite an adventure, and I feel very lucky to own two of his signed cards. Now that he has sadly passed away, and even though he participated in that single signing, I have a feeling that his autograph will remain one of the toughest to track down for future generations of Orioles autograph collectors.
