First Edition, Hardcover. Copyright 1962. Viking Press. Stated, "23rd Printing, March 1968".
Acceptable condition: Exlibrary, with the expected markings. No dust jacket. Covers are worn and stained, and the library roughly painted a stain on the spine, so the title would be easier to read. There is some stain that is on the back cover from that messy application. The outside book edges are tanning. The corners are bumped in and worn. The page faces are clean and UNMARKED, without notes, underlining, or highlighting.
