Illustration Magazine: Great Resource and Inspiration

One of the best resources for archival illustration I've found lately is Illustration magazine, published and edited by Dan Zimmer. This quarterly magazine is jammed with beautifully reproduced illustrations, magazine and book covers, and in-depth stories about illustrators of all kinds from 1900-1970. Of course the printed magazine is the best way to appreciate all this brilliant work, but their website has digital versions available of all previous issues. This is an amazing resource and learning guide. In addition, they have extensive links to other sites that will keep you looking and marveling for a long time.
