Phil Are Go has performed the vital service of close-cropping the finned beast from this 1959 Lincoln ad, for your clip-art pleasure, but not before adding a much-needed third axle. A vanilla two-axle model is also available.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
