Rob, I agree that Shean should be possible with a VE back, but given that he was only with Boston for 1909-1910 (and 4 games in 1912), I would not expect that he's on the K123/KNIT/Mino backs. I do find it interesting that he's one of the more common KNGO examples.
Back to the original thread purpose, here are some of my Matty cards from my back run. I haven't put together a nice scan compilation yet. I also recently added the Mello-Mint but haven't scanned it yet.
