its got a couple of bids, i have reported it to ebay, but no doubt they will do zilch!
realistically, ebay is in a hard place with posters and here's why - as Dale noted in a post last week, the average person is just looking for a poster. They have no idea what is the difference between an original and a repro, a bootleg, a reprint, a fanclub poster etc.
If they are only looking for an authentic theatrical poster -they need some education and factually, there's only so much anyone can do about that. You can lead a horse to water
but here's the issue for ebay - a poster is a poster is a poster
they have no way of understanding what the listing is supposed to be. No expertise in identifying fakes (or bootlegs or fanclub posters or authorized reprints etc).
so what can they do?
the person selling may not even know the difference, or if they do - they might not know they have a repro
this is of course, one reason why you buy from people who identify material properly (and why all dealers should absolutely be able to properly identify any item they are selling, without fail). But like all hobbies, there is a learning curve for all collectors. You aren't born with this data in your head.
