Huh. I wonder why I thought they were by the artists the Hildebrandt brothers. All this time, I was attributing them to the wrong person! Thanks for the correction.

The Hungry Tiger picture is from the website of David Lee Ingersoll. The guy's done some Baum Bugle illustrations in the past, I believe. Apparently, the image is from a planned revival of the Oz Squad comic. http://sentient39.comicgenesis.com/ozwhowho.html
