Erik Artur Olson (Ohlson, Olsson) (Halmstad 9 May 1901 – 1986) was a Swedish painter, illustrator, graphic artist, sculptor, theater decorator, and member of Halmstadgruppen.
In the evenings he cultivated his main interest, drawing and painting, by studying at Halmstad Technical School.
Late in the year 1930, he painted 'Handsken är kastad', (gloves are off), which is considered to be his first surrealist work.
Starting in the 1930s, his works participated at exhibitions in, for example, Copenhagen, London, Paris and New York.
In 1950 Olson converted to Catholicism and spent some of his later years rediscovering religious art.
