The job of political cartoonists is to push the envelope. But what happens when the size and shape of the envelope changes? That, in effect, is what has been happening ever since Hosni Mubarak was removed from power. Since then, the contours of permissible speech have been shifting constantly.

Jonathan Guyer maintains an extensive archive of Arabic caricature and comics, with hundreds of books and thousands of clippings. He'll discuss the first cartoons of Mubarak, the comic explosion since 2011, and what's in today's papers.

Jonathan Guyer is senior editor of the Cairo Review of Global Affairs. From 2012 to 2013, he was a Fulbright fellow researching political cartoons in Egypt. He has contributed to the New Yorker, Salon, Foreign Policy, and others. He blogs about Arabic comics and caricature at Oum Cartoon, http://oumcartoon.tumblr.com/.
