I believe Roy Kaplan did Space Duel CPO's many, many years ago (I know he did several different games back then). If he did, I have at least 1 and probably 2, as I bought 1 or 2 of every one he did back then. I'd sell one or both. Note up front though, Roy's are not die cut. Also, I'm not positive, but pretty sure that his repro CPO's were inkjet, not silkscreen. So there are some negatives assoicated with them. However the quality of his artwork is absolutely top notch. Spot dead on match to the original.
