I don't know but even before they are made available GUANO plans to offer an additional set of "OFFICIAL" GUANO cards which undoubtedly will be more beautiful and more expensive.
Get while the getting's good. I guess there is no law that will limit y'all to one each. Buy 'em by the gross. They won't spoil. Another way for GUANO to earn money. Isn't he resourceful? You keep him very happy by buying what he has to sell. He is counting on you to keep doing that until you die or run out of money...whichever comes first. Meanwhile it gives him lots of wiggle room which of course everyone would like to have. A financial cushion like no other in the world!
