Graphics Collectibles is selling original art from the Merrill archives. The 20 page catalog is $5. And I wouldn't have known about this but for Today's Inspiration, a blog devoted to illustrators of the 40s and 50s, that I've been following recently. Apparently Jean Woodcock acquired the Merrill archive a while ago, and wrote an article for Illustration Magazine about it (Issue #22, not the most recent one--I'm really playing catch up here!). Jean is, of course, the author of Paper Dolls of Famous Faces.
