One of the things I love most about conventions is the artists who visit and show off their sketchbooks and draw sketches for people. Even if you don't attend the convention, you can follow artists' blogs and see work they did during the con begin to trickle in. With last week's Baltimore Comic-Con in the rear-view, that's beginning to happen. Take, for example, Terry Moore, who did a phenomenal drawing of the girls from his Strangers in Paradise series dressed up as Slave Leia from Return of the Jedi.
You can view several additional pieces on his blog, including a Red Sonja and a piece he did for the Comic Book Legal Defense Fund!
