In 1922, Kurt Schwitters and Theo van Doesburg went on tour to spread the gospel of Dada. Their chaotic campaign of lectures and performances took Holland by storm, and this poster was their official merch. Like a contemporary band poster, this flier for the Kleine Dada Soirée was both an art object, a souvenir, and an event program, describing the evenings festivities including ragtime music by Erik Satie, insufferable abstract poetry by Schwitters, and something mysteriously called “Dadasofie” by Doesburg. The real highlight of the object though was its multilingual slogans, which included “Dada est contre le futur, Dada est mort, Dada est idiot, vive Dada!” — or “Dada is against the future, Dada is dead, Dada is idiotic, Long live Dada!”
