artist unknown; artist unknown
Ace Double D-69 (35 cent cover price) 1954 paperback. Condition is VG: tight and almost square; spine has some faint lines - but some of those are raised wrinkles as printed; light overall wear; the Padgett side has a binding fault that makes the right side miss the page block by 1/8" (see scan.) Age tanning is mild to moderate and uniform - better than what you expect in a 50 year old paperback. No stamps, marks or writing - a clean copy.
