Boston: Houghton Mifflin Company, 1967. Softcover. Very Good. Uncorrected proof of the first American edition. Illustrations by Pauline Baynes (illustrations not present in the proof, as issued). In plastic comb bound self-wrappers with applied label. Offsetting mostly confined to front wrap, a publisher's reply card addressed to Houghton Mifflin editor Anne Ford paperclipped to the front wrap, with subsequent rust from the clip, a sound and very good copy. Rare in this format.
