Movie poster questions?

[tdl797]

I bought a poster on eBay and before they shipped it I got one of those eBay e-mails showing they were listing another one with the exact same pictures. The poster was supposed to be an authentic movie theater poster. I got the poster and compared it to the photos. It is very close to the picture down to where the folds hit and seemingly random bumps on the paper, but there is a piece of tape on the poster in the eBay photo that is not on what I got. I am Messaging the seller and their sentence structure is all over the place. They don't address all my questions. In my original Message I told them I was possibly interested in 2 other posters and they completely ignored it. Just odd all around. Ignoring the chance to sell 3 posters instead of 1 made me think that they don't care about money, so that lent more to it being authentic in my mind.

No, I'm not gullible. They have a perfect rating with 10,000's of ratings.

If there is anyone who knows details on mid 80's era authentic theatrical posters and is willing to help, please send me a PM.
