Loud, irreverent, dangerous, and sexy could be descriptors for both Harley Quinn and Tank Girl. Artist Valhalla Halvorson has created a mashup of both of these interesting characters. This art is also available on a T-shirt and in a variety of colors.
Just for contrast I've included the original Tank Girl art that inspired Halvorson's mashup. There are lots of great details that were translated over into Harley Quinn's style. Via: Geek Alerts.
