Harry Potter and the Philosopher's stone (ISBN version)

Country of origin UK quad poster for this British film.-N.B.-This is the ISBN version distributed via book shops during the first release.-It was part of the same print run as the regular cinema poster and was identical in every way to the standard quad apart from the addition of an ISBN reference number in the lower right hand corner.-Selling at a discount to the non-ISBN style, these are an excellent way to get a genuine item at half the price of the cinema version.
