Boston: Houghton Mifflin, 1962. Illustrated by Lois & Louis Darling. 8vo, green cloth, d.w. Boston: Houghton Mifflin, 1962. First Edition. A very good(+) copy in a very good(-) dust wrapper. The dust wrapper very slightly chipped at the edges, with some creasing and closed tears in the lower right corner which has been reinforced with clear tape on the verso; the book has very slightly rubbed corners, otherwise a very good copy of this landmark book.
