Harald Damsleth (16 August 1906 – 1 March 1971) was a Norwegian cartoonist, illustrator and ad-man. Damsleth was a member of Norway’s home-grown fascist party, Nasjonal Samling, and became their most ardent propagandist after they came to power under German occupation in 1942.
Damsleth is best known as a pro-Nazi propagandist for his posters for Nasjonal Samling (NS) during World War II.
