...Well, we at least have the proof, that all the Rubik Puzzles & others, were at one time EASILY available !
Way back then, if someone would have said, " In 20 years or so, all theses puzzles will be really rare
and several puzzle fanatics around the world will be hunting them down on their computers on the internet,
at a place called eBay...and paying double, triple and quadruple, if not more" ,
People would have probably said:
_Maybe I should pick up a couple of the New Rubik UFO puzzles once they come out in january,
and wait 20 years and see what happens... !
