Martin Kellermanis a Swedish cartoonist, mostly known as the creator of the successful strip 'Rocky', published in many big, mostly Swedish, newspapers. The semi-autobiographical cartoon 'Rocky' was created after he was just fired from his position as a cartoonist for the gentlemen's magazine Aktuell Rapport, was dumped by his girlfriend and thrown out of his subleased apartment. 'Rocky' has since then, among other things, been published as a magazine, twelve books with cartoons, wall calendar, Christmas calendar, and a stage play, touring around Sweden. Kellerman has also worked as an illustrator for other works.
