Notes:
• First SFBC edition (not stated) • First printing has gutter code "16J" [verified] on page 219, indicates a printing in April 1968. • "Jacket design by Adelson & Eichinger" from the inside rear jacket flap. Since the cover is largely text this sounds like a firm and thus is entered in the field as one entity rather than two separate artists.
