For anyone who follows comics news, you may have heard that recently the Museum of Comics and Cartoon Art bit the dust... well, not exactly. They've merged with the Society of Illustrators and now have permanent gallery space alongside works from the Society's collection. Here's a great article here: "When Museums Cohabitate" by Kevin McCloskey.
So, the next time you visit the Society, you're also visiting MoCCA. And it's all still free. Yippee!!
