Jansson continued painting and writing for the rest of her life, although her contributions to the Moomin series became rare after 1970. In 1966 she was awarded the Hans Christian Andersen Award.

Her fame spread quickly and she became Finland's most widely read author abroad. She went on to write six more Moomin books, a number of picture books and comic strips. This first book was hardly noticed, but the next Moomin books, Comet in Moominland (1946) and Finn Family Moomintroll (1948), made her famous. She said later that the war had depressed her and she had wanted to write something naïve and innocent. Jansson wrote and illustrated her first Moomin book, The Moomins and the Great Flood, in 1945, during World War II. She displayed a number of artworks in exhibitions during the 30s and early 40s, and her first solo exhibition was held in 1943. She studied at University College of Arts, Crafts and Design in Stockholm in 1930–33, the Graphic School of the Finnish Academy of Fine Arts]] in 1933–1937 and finally at L'École d'Adrien Holy and L'École des Beaux-Arts in Paris in 1938. Tove's siblings also became artists: Per Olov Jansson became a photographer and Lars Jansson an author and cartoonist. Her family, part of the Swedish-speaking (Swedish: finlandssvensk) minority of Finland, was an artistic one: her father Viktor Jansson was a sculptor and her mother Signe Hammarsten-Jansson was a graphic designer and illustrator. Tove Jansson was born in Helsinki, Finland, which was then a part of the Grand Duchy of Finland.
