In an article for Wired.com, The Hero Initiative's president Jim McLauchlin wrote up a piece announcing the retirement of legendary Mad Magazine artist Jim Davis at the young age of 90. Davis is retiring not because he can't draw anymore, he just can't draw to his own standards. Besides Mad, Davis worked on movie posters as well as doing covers for TV Guide back in the 1970's when it had a 20 million print circulation.
IDW recently published Jack Davis' EC Stories Artist's Edition. For more on Jack Davis, click the wired link below for McLauchlin's article.
