The New Yorker cartoon issue is shipping now, although I haven't looked at mine yet. They've got some online features including a selection of Luckovich cartoons and a Bob Mankoff Q&A. I had a drink with Mankoff once, along with some other cartoonists. He's got a keen appreciation of humor and cartooning as well as a very good grasp of the economics of cartooning.
