Mandel Karlsson

The series is now published in its own bi-weekly comic book, 91:an, and also as a single strip in the popular weekly women's magazine Året Runt.

Mandel Karlsson is based on two people Rudolf Petersson met during his national service in the Halland Regiment.

During the first three decades, Mandel was fond of fighting, but became a less aggressive, gentler character during the highly successful period of Nils Egerbrandt's work, starting in the 1960s.

His number is "91", thus he is widely known in Sweden as "91:an Karlsson", although in the comic strip itself he is almost always referred to as Mandel (English: Almond), or simply 91:an.

His sidekick, Lars Fjodor Axelsson, is a brasher, naughtier character, and has frequently tried to compete with Mandel for the attentions of Elvira.
