Harry Potter: A Hogwarts acceptance letter with envelope from The Philosopher's Stone,
Warner Bros., 2001,
"The Cupboard Under The Stairs, 4, Privet Drive, Little Whinging, SURREY" printed in green ink on the front, bearing the Hogwarts crest stamp on the back above an unbroken, red wax seal with an "H" for Hogwarts, accompanied by a letter of provenance on Harry Potter Productions letterhead confirming that this is one of only a limited number of props given out by the studios for charity. Together with a photocopy of the acceptance letter in the envelope and a photocopied magazine cover showing Daniel Radcliffe with one of these letters. Used in the unforgettable scene in which dozens of these envelopes arrive by "owl post" and swirl around Harry's living room, 5in x 7in (12.5cm x 17.5cm)
