I think you should send your customers whatever it is they want. If they want both types send them. If not, don't.
No, you need not picture both varieties in your catalog, although I picture them in my CyberGuide. But, the opposite insert version could be mentioned.
Like I said earlier, I DO collect these variations. I will admit though that before I decided to do so, I first checked my specific collecting area (riverboats and indians), to see how many possibilites there were. Since there were less than 50 I decided it was doable.
