while these fantasy cards are cool to own, it's one more way that newbies can get taken, just like any other poster reproduction and they should be marked visibly on front or back for exactly what they are to prevent any confusion down the road as the items will outlast all of us.
I have Star Wars hairy belt posters. I would like to sell them, but I don't want them falling into the wrong hands, so I don't sell them
I also have reservations about whether all the ones being sold are actually "original fakes" or later fakes.
Some dealers seem to auction them endlessly and knowing that the original source had sold them out many moons ago makes one wonder how so many are for sale now when the print runs were low to begin with.
