Quoted from KevinCPR:
It could work that way, certainly. But that is the question. Do we begin the hunt for the rare one or the stock one, or both? If the layout is done in a way that it's add/subtract naughtiness (and no other version/layout changes), then yes possibly everything we need might be found on one glass. So demand for the naughty version has to be considered of even being worth the hunt or not.
A decent stock one could be lined up with a donor immediately. The naughty version is a different story. That's going to take some hunting, and some glasses took us year(s), let alone to find a donor willing to part with theirs for a few weeks to take a trip to the Arizona cruze studio.
Dann Frank had at least 3 of the 4 variations of the Bad Cats Backglass. Not sure if he still does.
I forget all the variations but did personally see 3 distinct glasses in person about 9 years ago or so
Differences were the game title mirrored, in solid black and in orange/black stripes.
At least 1 of them had the roof tiles and brick outlines printed on the front rather than a light effect from behind.
Then there is the snake head instead of Python's head.
Some of these can be seen on the flyer.
I don't recall seeing the rumored condom by the garbage can.
