**While I believe this description to be accurate, this lot is being sold as-is with no returns** You are bidding on a lot of seven (7) mass market paperback Edgar Rice Burroughs novels from the 1960s, 1970s, and 1980s. These books are used, and would be the typical quality that you would see in a used book store. They all have some common characteristics, and a few have unique defects that will be noted in the book list below. The common characteristics that all the books have are: Their spines tilt and have some level of creasing. The covers have some wear and some creasing. The pages are tanning / browning with age. Any additional defects will be noted below (if they have no further notes, then they just have the common characteristics). The books that you will receive are: A Princess of Mars (Mars Series #1) - acceptable condition; this one is in the worst condition of the lot; the pages and covers have some water staining. The book also has significant foxing on the inside of both covers and first and last pages (brown or yellowish spots and splotches). See pictures for both the staining and foxing. Still quite readable, but has these flaws. There is also an old price written on the first page in what appears to be pencil (it can probably be erased, but I haven't tried). Ballantine Books, Fourth Printing, February 1969 The Gods of Mars (Mars Series #2) - fair condition; this one has some pretty heavy foxing, but not as bad as book #1 above (see picture - it also has this in the back). There is also an old price written on the first page in what appears to be pencil. Ballantine Books, Fourth Printing, February 1969 Thuvia, Maid of Mars (Mars Series #4) - good condition; just the common characteristics above; Ballantine Books / Del Ray, Eleventh U.S. Printing, May 1979 The Chessmen of Mars (Mars Series #5) - good condition; just the common characteristics above; Ballantine Books / Del Ray, Eleventh U.S. Printing, September 1980 A Fighting Man of Mars (Mars Series #7) - good condition; just the common characteristics above; Ballantine Books / Del Ray, Eleventh U.S. Printing, Fourth Revised U.S. Printing, August 1980 Tarzan of the Apes (Tarzan #1) - fair+ condition; has some foxing (not as bad as the books above); Ballantine Books, First Special Printing, January 1976 The Return of Tarzan (Tarzan #2) - fair+ condition; has some light foxing, some pages are browner than the others; Ballantine Books, Thirteenth Printing, December 1979 See the pictures for more details.
