The Royal Book of Oz Illustrated Ruth Plumly Thompson

The Royal Book of Oz (1921) is the fifteenth in the series of Oz books, and the first to be written after L. Frank Baum's death. The Scarecrow decides to search for his family tree and winds up discovering that he is the long-lost Emperor of the Silver Island. Along the way, he meets such colorful characters as the A-B-Sea Serpent, the lumpy mud men. The Scarecrow digs at the base of the beanpole and slides down the beanpole to the Silver Islands. The islanders hail him as the Emperor, returned to save his people. The islanders, however, are reluctant to let him go, and plot to change him back into his human form, an 85-year-old man.
