Notes: • © 1965 No other date, edition, printing or number line • The catalog # is not a typo, as there is also an edition with the same price and cover with #17260 • That edition was published in 1969, per Stuart Wells Ace Notebooks, and this edition likely precedes that one as all later Ace printings are numerically in order from the catalog #17260, but Tuck does not list it so definitely post-1968 • It is unlikely Ace would publish under 17260, switch to 17620 and then revert [but then it is Ace!!] • Cover by John Schoenherr on copyright page, no visible signature on the artwork • The ToC lists a map on page 542 but pages [542-545] are not numbered • OCLC has no record specific to the catalog #
