"Wonder Woman in Vietnam" from DC: The New Frontier #2 (DC, 2004) by Darwyn Cooke
I hardly need to sell anyone on Darwyn Cooke's New Frontier. It won a trifecta of comics awards (Eisner, Harvey, and Shuster), was collected in both standard and Absolute editions, and was even made into an animated movie. It takes place in the 1950s and acts as a bridge between Golden Age characters and Silver Age ones, and its Wonder Woman, pictured above, is a lot of fun. Kind of like DC's version of Marvel's Hercules, when you think about it.
