Uncorrected proof copy, second state. Two proof copies were issued before the publication of the third book in the Harry Potter series: the first was issued in purple wrappers, and the second, with editorial work undertaken on the text throughout, in green wrappers.
Bloomsbury only issued proof copies for the first three Harry Potter novels. The publishers have no accurate figures but suggest 200 copies of Harry Potter and the Philosopher's Stone, and between 200 and 300 copies of Harry Potter and the Chamber of Secrets. The number of proof copies of Harry Potter and the Prisoner of Azkaban is especially vague. Errington notes that an unconfirmed figure of 50 copies is accepted for the purple proof (with some records at Bloomsbury suggesting 150 copies), and that 250 copies of the green proofs is accepted (with records at Bloomsbury noting 150 copies).
Octavo. Original green and white wrappers, spine and front wrapper lettered in white and black. Housed in a green cloth flat-back box by the Chelsea Bindery. Front joints slightly rubbed, minor creases to wrappers, minimal staining to pp. 313-16 and rear wrapper; a near-fine copy. Errington AA4(b).
