I have bound original NGM complete for these three years. As is typical for these bindings, there are no original covers or advertisements, All three vols. have indexes. Bindings are 1/4 Leather/ Marbelled boards. No maps. Internal bindings are very good++, original spacers for maps present. The external bindings and covers are period and in poor condition. Covers have separated from the 1900 book and should be rebacked. External leather is heavily chipped and frail in all 3 volumes. Internal Papers for 1900 VG++, 1902 VG++ and 1904 VG+ except for 4 pages in June issue with has very mild top paper edge chipping 1 to 3 mm deep.
These 3 editions would be excellent candidates for rebinding to match your existing sets.
THESE ARE NOT REPRINTS. Will send jpgs if interested.
If interested, please contact me. I prefer trades and have attached a wants list.
