Notes:
• No printing history; no number line [seventh printing by catalog # progression] • "This Ace edition follows the text of the original magazine novels published in 1925." • "With exciting cover art by Frank Frazetta" on back cover, no visible signature on the artwork • Probably precedes the September 1978 edition as the address is 1120 Avenue of the Americas, and that edition's address is 360 Park Avenue. The two ads of 73 (Conan) and 6H (Lieber) may help place the date.
