Here’s one of the more unusual Wizard of Oz books, Who’s Who in Oz by Jack Snow. Copyright 1954 by Reilly & Lee, this is a 1st edition w/o dust jacket. This book lists all the characters in prior Oz novels, with a brief blurb about them. Many single color illustrations. Also contains very useful appendices–the first containing synopses of the prior 39 Oz books, and the second, biographical sketches of the various authors. With brown illustrated endpapers–maps of Oz and the magical countries outside its borders.
The book is in very good overall condition, except on several pages in the back, there are some pencil checkmarks and writing where someone has noted which Oz books they have in their collection. The exterior cloth is in quite nice condition, and hinges are tight.
