Zap Comix #1, Robert Crumb, 1968

The comic that turned a handful of scattered experiments into a movement. Robert Crumb drew all of it, and Don Donahue's Apex Novelties put it out in February 1968, with Donahue and Dana Crumb among those selling copies on Haight Street. "Fair warning: for adult intellectuals only!" runs across the top, and the cover sets the Zap look for good: Mr. Natural riding a bulbous yellow jalopy through the city, a big hand-lettered logo and a mock Comics Code stamp "approved by the Ghost Writers in the Sky." This copy carries a 35-cent price; the very first printing sold for 25 cents.
