That they come from series so far apart and that the card border is printed makes me think it's likely fake. I've seen less likely things pass grading, so a bunch of dealers/auctions thinking it's real is no surprise.
If it was real and I was shown the card at a show, and I had the money I'd have made an offer. it seems they didn't like it
that much.
The other sort of multiple impression is a weird one, during press adjustment the registration can be far out of adjustment, while adjusting, the press cane be running, and print to the blanket multiple times but less well inked each time. Then when a sheet is pulled to check it will have multiple impressions. Stranger when it's a multi color press, and the location of the paper is what moves the registration.
Like this, black and Magenta, so two color press. Way off at first, but brought pretty close over 6-7 revolutions. Blue and yellow also, but only a couple revolutions.
