After reading this older thread (w/ many of the same folks in this one), I'm now w/ most of the others in believing that these card are authentic. Here's the link:
Link. The thing that is very convincing to me are the arguments from Rhett and Frank that many of the images in these card are extremely rare. If someone was trying to make a reprint set, why would they use such difficult to find images? They would use the common ones from the E120-80 or W575 sets.
I think someone told the original seller that Brian met that the cards were fake. Someone that person trusted as a knowledgeable collector. That is why he seemed so honest when talking to Brian and priced the cards so low. Maybe they simply made a mistake at that time thinking the cards were fake because the set was unique and not catalogued.
