The New Yorker art editor, Françoise Mouly has a Tumblr and it is awesome. In addition to cool miscellania like the '80s photo above, Mouly also runs a weekly, "Theme of the Week" contest where artists can submit covers based on themes like this week's "In Like a Lion, Out Like a Lamb."
Mouly says that "this blog and contest are informal and not affiliated with The New Yorker magazine, but I’m always on the lookout for ideas. When I find them, I’ll get in touch with the artist, all on a case by case basis." She also asks artists to "keep submissions confidential in case they are later selected for publication," so it's more than just for fun.
