On the Vintage Ads LJ group, the infinitely amazing Man Writing Slash posts a collection of Ethyl gasoline ads from 1950-1952 that emphasize the advantages of leaded gasoline through humorous graphic comparisons -- a kind of precursor to today's HSBC "We see the world differently" ads.
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.
