Uncorrected proof copy, signed and dated by the author on the half-title, "29-6-98, J.K.Rowling". This copy was therefore signed three days before publication of the first edition. Errington notes that the print run is unconfirmed and states that the publisher's archives merely suggest "between 200 and 300 copies". The text was slightly reset for the first edition.
Octavo. Original blue and white wrappers printed in black. With proof dust jacket. Housed in a blue quarter morocco solander box by the Chelsea Bindery.
Fine condition.
