Casual Friday? You’re in Washington—-you can do better than that. How about Anti-War Cartoon Friday? Once upon a time, Americans used to protest wars they didn’t believe in and cartoonists helped fight the anti-“good fight” fight. My, how the world has changed. Tonight, editor Craig Yoe will be showing a selection of cartoons from The Great Anti-War Cartoons (IDW, $25) by greats like Honoré Daumier, Louis Raemaeker, Ding Darling, Robert Crumb, and Tomi Ungerer. Local cartoon book collector Warren Bernard is bringing his rare, original copies of The Masses, the first Life Magazine, Le Rire Rouge, and De Notenkraker, from which some book’s cartoons have been copied, and you can marvel at the vibrancy of the original printings.

Friday April 16, Politics and Prose (5015 Connecticut Ave. NW, 202-364-1919) from 7 to 8 p.m.
