Here is a 1st edition Wizard of Oz book titled The Gnome King of Oz by Ruth Plumly Thompson, with 12 color plates by John R. Neill. Published by Reilly & Lee in 1927. The book also has Illustrated endpapers by Neill.
This book is in good but not very good condition–exterior has wear to pastedown, a clean spine, and some color loss on back cover. Inside, both hinges are quite loose with mull (webbing) showing. Endpapers have age toning. Book Belongs to page is blank wth a small stain on back. Pages are generally clean without writing or tears. All 12 color plates are present and in good condition except the last one is loose and laid in. A hard to find Thompson 1st!
