"Kabumpo In Oz", by Ruth Plumly Thompson, illustrated by John R. Neill; published by Reilly & Lee Company, Chicago, 1922. Early printing with color plates.

"Kabumpo in Oz" (1922) is the sixteenth Oz book, and the second written by Ruth Plumly Thompson. It was the first Oz book fully credited to her. Her first, "The Royal Book of Oz", was credited to L. Frank Baum on the cover.

During Prince Pompadore of Pumperdink's eighteenth birthday celebration, his birthday cake explodes, revealing a magic scroll, a magic mirror, and a doorknob. The scroll warns the prince that if he doesn't wed a "proper princess" within seven days, his entire kingdom will disappear. The prince, along with the kingdom's wise elephant Kabumpo, set off on an adventure to the Emerald City so Pompa can marry Princess Ozma, the only "proper princess" the Elegant Elephant can think of as worthy of his prince.
Meanwhile, Ruggedo the Gnome King (Thompson "corrected" Baum's spelling of "Nome") finds Glegg's Box of Mixed Magic while tunneling under the Emerald City. After he brings a wooden doll, Peg Amy, to life, and makes Wag the rabbit the size of a man, Ruggedo turns himself into a giant. This means that Ozma's palace gets stuck on his head, and in a panic he runs off to Ev with it..

John Rea Neill (Philadelphia, Pennsylvania, November 12, 1877 - September 13, 1943) was a magazine and children's book illustrator primarily known for illustrating more than forty stories set in the Land of Oz, including L. Frank Baum's, Ruth Plumly Thompson' s, and three of his own. His pen-and ink drawings have become identified almost exclusively with the Oz series. Neill brought his own unique flair to the illustrations, showing more artistic representations of the characters as well as beautiful paintings of numerous scenes. In fact, he was later named the Imperial Illustrator of Oz.
