It is rare for anyone to have an original poster signed, as the majority of signatures are on pieces of paper, photographs and video/DVD sleeves. It is unusual to have the film's poster with you when you try to obtain signatures. This was where it all begun back in 1977, when George Lucas brought us the beginning of the Star Wars empire.
