Kitchen Sink (1970-77)
Robert Crumb’s Mr. Natural is one of the most popular and enduring characters to emerge from underground comics, definitively surpassed only by Gilbert Shelton’s Fabulous Furry Freak Brothers. Mr. Natural appeared in all manner of publications in the ’60s prior to starring in his own comic book and while his popularity today is a tiny fraction of what it was 40 years ago, his likeness can still be found on t-shirts, posters and various collectibles. The Fantagraphics book compilation of his comics was reprinted in a hardcover edition as recently as 2010.
An icon of the underground scene, Mr Natural “Keep On Truckin'” shirts still sell today.
