Here is a copy of Billy in Bunbury, put out by Royal Baking Company and written anonymously by Oz author Ruth Plumly Thompson. Beautiful full-color illustrations on every page by Gertrude Kay (some signed). Also verse and recipes. According to Pacific Book Auction, Billy in Bunbury came out in 1925. (Other Thompson “Fairy Books” came out as follows: The Little Gingerbread Main in 1923, The Comical Cruises of Captain Cooky in 1926, and The Prince of the Gelatin Isles in 1926). They were Royal Baking “giveaways” and fragile, so not many survived. A nice addition to that Oz collector who has almost everything. 16 pages. This copy with corner folds and small amount of paper loss at top edge about “B”; moderate spine wear but all pages attached and in very good condition inside with light occasional soiling. No writing.
