Otto G Carlsund

Probably the archeologist Olof Janse (author of "Grottmannens gåta"), later professor in USA. Thereafter in the possession of the family.

Otto G Carlsund was a Swedish painter, theorist and critic. Whilst in Paris in 1924, he formed a friendship with Fernand Léger, Ozenfant and Piet Mondrian and became the representative of Swedish synthetic cubism, purism, and neoplasticism. It was between the years of 1932 – 45 when Carlsund was the most active as a critic, but rediscovered his passion for nonfigurative painting in his last years. His paintings were often intended as preliminary studies for wall paintings. In 1929, he co-founded the group Art Concret in Paris with van Doesburg and Hélion, publishing its manifesto.
