On March 28, 1932, the Dutch Onafhankelijke Socialistische Partij (Independent Socialist Party) was established. It was a left wing split off from the social-democratic party. Meijer Bleekrode designed this poster on the occasion of the 1933 elections. In 1935 the OSP joined the Revolutionary Socialist Workers Party.
