Here is Yankee in Oz, a book published by the Wizard of Oz Club in 1972, signed on the front endpaper by the illustrator Dick Martin. This is the 1st hardcover printing, with the light blue cloth over board binding. Oversized, 94 pages, illustrated in black and white. This edition never had a dust jacket, although the color wraps from the softcover edition are bound inside this hardcover book.
Book is in fine condition–exterior bright and beautiful. Interior is fine, tight and unmarked. An very nice copy!
