One of my favorite publishing stories is Mark Askwith's tale of the microscopic "Printed by Mindless Acid Freaks" slogan that Coach House Press used to print underneath their logo on their books.
Turns out they're not the only ones who like to hide cool stuff in the fine-print. A med student ws reading through the copyright notice on a textbook when he discovered an offer of a free car to people who read the fine-print. He drove away with a red '65 T-bird convertible. 60,000 copies of the textbook were shipped and only five people responded to the offer.LinkDiscuss (via Ribbit)
