I give you Sugar Krinkles, bearing the finest cereal package art in the history of the world, a relic of 1950, the vintage year for such work. Be sure to click through onto the whole Vintage Ads post, wherein the epic Mr Man Writing Slash has also embedded a clowns-drinking-whisky ad that will make you scream with terror and delight.
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.
