Art Spiegelman Cover For New Statesman Was Pulled After A Dispute Involving A Muhammed Comic
Maren Williams has a really thorough write-up here about an Art Spiegelman cover for a Neil Gaiman/Amanda Palmer guest-edited magazine. You should read it for the particulars. The cover in question is here big as life. The comic that was left out of the issue and the subject of negotiations that resulted in the cover being pulled is here.
That's a pretty incredible series of events. Two things I find interesting: 1) the magazine had apparently made a decision at the editorial level that made Spiegelman's comic unusable by them because of its arch visual evocation of Muhammed, and 2) for some reason this couldn't be communicated right away to Spiegelman, Gaiman and Palmer.
