Attempting to promulgate Dada ideas throughout Europe, Tristan Tzara launched the art and literature review Dada. Dada Issue number 3 violated all the rules and conventions in typography and layout and undermined established notions of order and logic. The unconventional and experimental design was matched only by the radical declarations contained within the third issue of Dada. Included is Tzara's "Dada Manifesto of 1918," which was read at Meise Hall in Zurich on July 23, 1918, and is perhaps the most important of the Dadaist manifestos.
