Mandel Karlsson is based on two people Rudolf Petersson met during his national service in the
Halland Regiment. He based his characters 91:an Karlsson and 87:an Axelsson on a man named
Smålandian. Mandel Karlsson is written as a
sympathetic character. 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. Mandel Karlsson is a young man, aged perhaps 20 or 21, who is a
military conscript in the
Swedish Army. He is attached to the fictional Klackamo Regiment. 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. Mandel is the son of Mandolina and Johan Karlsson. From a working-class rural background, he often uses colloquial dialect expressions and vocabulary and possesses a connection to animals. He is a well-known
accordionist. Previously, he was also a heavy
smoker. He is very keen on his love interest Elvira Olsson, although they have regular fall-outs. Elvira often has to take the initiative in romantic matters. His
sidekick, Lars Fjodor Axelsson, is a brasher, naughtier character, and has frequently tried to compete with Mandel for the attentions of Elvira. Mandel has been known to express a lively interest in other young ladies who meet his acquaintance, but less so than other conscripts at the Klackamo Regiment. Mandel is well liked by the senior officers at the regiment and is quickly forgiven for his frequent transgressions of the rules. He often does chores for Överste Gyllenskalp at home, for example walking his
Great Dane, Caesar. ==Media adaptations==
