Stupid (art movement)
The Stupid group aimed to address sociopolitical issues through an art of proletarian character. Seiwert and Räderscheidt were at the time active in the local Dada scene. Räderscheidt's studio was their base of operations, but by 1920 he had abandoned the constructivist style. The group  exhibited together and issued a publication, "Stupid 1", before disbanding.
