One of only a handful of uncorrected error cards in the OPC series, both the player and the card do not appear in the Topps series, so this is exclusively an OPC error. The confusion surrounding this card stems from the fact that there were two Bob Kelly’s in the league. One, named “John Robert “Battleship” Kelly” changed his name to J. Bob Kelly for the league to help make it easier. It didn’t. The intended transaction was when J. Bob Kelly was traded to the Oilers from Chicago, but instead they grabbed Bob Kelly from the Flyers. So, correct card, wrong image.
Right card, wrong image
This is how the card should have looked
