The Enchanted Island of Yew, from 1903, is one of L. Frank Baum's less "Americanized" stories. As with Queen Zixi of Ix, I think this tale has more of a long ago and far away sensibility, and is a bit more European in style.
This book was illustrated by Fanny Cory, who also illustrated The Master Key. For this title, Bobbs-Merrill tried a different approach. There are 8 full color plates, but the text illustrations are printed in orange under the actual text. It's a fun look for the book, but the drawings are difficult to distinguish - I'd much prefer to see them on their own.
M.A. Donohue publishers re-used the cover design from this title for another book, a collection of stories and fairy tales. I ran across one in a small antique mall once and was quite surprised to recognize the cover - since then I've seen a copy of it featured in the Baum Bugle. I had passed up the copy I saw, as it was in pretty rough condition!
