He just published ILLO 2, which features interviews with Michael Cho, Nancy Stahl, and Zina Saunders. Somehow I'm lucky and they included me too.
It is difficult to convey the extent of the coverage is about each person without actually seeing the question, here each page. Go to a newsstand and pick up for Mr. Zimmer may continue to make future problems. There are many other deserving illustrators he has yet to cover.
