I have since found what looks like a very nice centered Mike Bossy OPC RC. (Just waiting for it to be delivered)
If it is as nice as it looks in the scans/pics, I think I am going to be very happy with it?
A couple small corner touches/dings, but the centering, which is super tough with his OPC card, looks to be spot on. Fingers crossed.
This card just arrived today, which is my first correct era playing card of his. Looking forward to collecting more.
