The first Mr. Natural strip, “Mr. Natural: The Zen Master“, appeared in the premiere issue of the Philadelphia-based underground newspaper Yarrowstalks on 5 May 1967. When editor Brian Zahn proposed to Crumb to fill the entire third issue with his comix, Crumb created Flakey Foont and several other characters.
Mr. Natural made appearances in other underground newspapers such as the East Village Other, which published the strips “Mr. Natural Meets God” and “Mr. Natural Repents” among others. He made his first official comix appearance in Zap Comix #1 (Feb. 1968). Mr. Natural also appeared in early underground comix titles like Bijou Funnies, and Yellow Dog. He was a regular in Zap for the balance of the 1960s until appearing in his own three-issue title, originally co-published by The San Francisco Comic Book Company and Apex Novelties.
