I have one at my desk. The back is light gray. And it should be paper stuck to thicker cardboard.

This is from my last collection. I am too lazy to scan the one I have...but the backs are light gray...

Thank you Todd and Leon. Much appreciated. This is the card. Overall a nice example.
Most of the Butterfinger Overprints have come across have been Cardinals. And I have always enjoyed them. They unlike the base cards are very easy to display and share.
It was almost sad that when I completed my R310 set it sat in a box that probably only saw the light of day a handful of times in 3 plus decades. They were just too fragile to handle.
