I figured I'd toss this out to the larger community here, but are there any 1/1 cards (preferably sports, but a good non-sport example is welcome) that are truly unique and aren't some form of parallel (color, foil, jersey, buyback, etc).
The only ones that come to mind are sketch cards and cut autos or some oddity (like a swatch of hair), but I'm really not thinking in these terms. I'm thinking more in terms of a standard production insert card. A insert set with a design that is completely unique to itself. Is there anything like this out there?
