Hey Bob. There is a variant ( recurring print defect) to that card too . It was listed in the Topps Super set that sold recently. On the back it can be found with the Topps on the bottom touching the border or with some space and a slash through the PP in Topps. I found one after that listing and will post when I get a chance
