Harry Potter and the Philosopher's Stone (int'l boat advance)

Released in the USA as Harry Potter and the Sorceror's Stone, this was the first of the Harry Potter books to be made into a film. This particular poster is the international advance so it has the correct British name (Philosopher's stone). And, as this is the advance poster, this holds a special place in Harry Potter history as this is effectively the very first of all the Harry Potter movie posters. Rolled in excellent condition.
