What I envision here is an Andy Warhol-like creation...a sculpture of mustelid roadkill of your choice nicely embossed on a section of road and hand-painted to the most realistic (and goriest, if so desired) of effects, and encased in a cubicle of glass...I like the weasel, crumpled but whole, with just a blemish of blood, and perpendicular to the middle-line so it crosses his body in the center for a surreal imagery-combo of the cross and "x marks the spot." No skid marks, just a clean squash. And a double white-line, of course. Should go for at least $45,000 in any reputable gallery when done.

Choose your specimen! Here's a link to an old thread to help you out:
