First edition from 1963 of Unexplored Territory in Oz by Robert R. Pattrick, published by the International Wizard of Oz Club. Must have been one of their earliest publications other than the Baum Bugle. Instead of the several later printings with 36 pages, this printing has only 32 pages (no illustrations) and is perfect bound instead of stapled. It appears to be laid out with a typewriter. Contents are four interesting essays: Oz vs Authors, The Early History of Oz, Oz Magic, Books in Oz and a detailed bibliography. In perfect condition inside, but with a vertical brown line on the cover as shown. Light wear to bottom of spine and corners.
