I've long been a huge fan of The New Yorker cartoons. They are almost uncanny in combining the visual and verbal aspects of humor. The combination of the two makes for a really good joke.
This 2012 Calendar/Planner presents some of the most amusing, and largely understated, cartoons from the New Yorker's collection. The calendar is organized in terms of the weeks, and there is one cartoon per week. There is enough space for each date to write in a few notes or appointments, but if you are someone who keeps a fairly packed schedule than you will find this quite inadequate.
Cartoonists that are featured in this collection include Joe Dator, Michael Maslin, Paul Noth, David Sipress, Tom Toro, Christopher Weyant, Bob Eckstein, and many others.
Overall, this is a very functional and entertaining calendar that is quite adequate for most people's scheduling needs.
