Am not really up on this or other such BTTF posters, but always read of their stories.
On the emp site, "The VHS video box for the first movie contained an order form for this poster, but it was almost immediately sold out and the company went out of business!"
How does a company immediately sell out of stock, and then immediately go out of business? Cash flow? Curious about this if anyone has info. As for the poster, was also not aware commercial film posters could go for so much - bearing in mind the chaps and chapesses on this site are all about originality.
