Atheneum, 1969. Paper Back. Used - Very Good. Item #231834
Some external wear to cover. Bottom corner of front cover creased. Edgewear. Also inside first page is clipped. Text is clean & without markings. Spine solid. Stated 'First Edition', but there seems to have been a hardcover edition published in 1968, which would make that edition the First Edition, not this paperback. I have not seen the hardcover, but these hardbound 'true firsts' do seem to exist.
