All first editions; volumes 2, 3, 4, and 6 come with the original advertising pamphlets. All volumes show signs of aging, including yellowing, soiling, staining, and creasing. Some volumes have split spines. The particularly dirty areas are shown in images 13 and later, but a complete check of all pages has not been done, so there may be oversights. Volume 1 is in particularly poor condition overall. These items have been stored at home for a long time and are old. Please examine the images carefully and only purchase if you understand that they are used items.
