I dropped the ball on this one and am now having buyer's remorse* (already paid). Does anyone have any information on these posters? There are a number of them on ebay selling for anywhere from 300-1200, but web searches result in no mention of anything like them except ebay listings. Do you guys think these are legitimate/authentic signatures?

*Normally when I am skeptical of something's authenticity I just skip it, but red flags didn't start popping up until I had made payment and the payment receipt arrived.
