When I consigned one of my T207 sets to Mastro Auctions back around 2002 or so I was told that in taking scans of the cards they had somehow "lost" the red Cycle back Lowdermilk card from the set. I was reimbursed and the auction went on without that card (EXish condition) but I always wondered what happened to it. The "official" explanation was that someone "probably accidentally threw it away during the photographing process."
Yeah, I thought the same thing you are thinking...
