"For the next two weeks, The New Yorker invites readers, budding or would-be cartoonists (as well as bona-fide pros and assorted graffiti artists of course) to create their own humorous version of Eustace Tilley, the iconic dandy who appeared on the first cover in 1925 and has returned for nearly every anniversary issue since. Valid entries will be displayed on a dedicated Flick’r site for all the world to see. Up to twenty winning entries, selected by New Yorker editors, will be published on newyorker.com to commemorate the magazine’s 83rd anniversary."
This looks like it could be fun! Visit The New Yorker website for rules and details.
