From 15 August to 30 September 1923 the Bauhaus held an exhibition in Weimar, at the height of the inflation. Walter Gropius opened it with a lecture called Kunst und Technik – eine neue Einheit, art and technology, a new unity. The largest exhibit was the model house Am Horn.
From 1922 the Bauhaus potters had developed prototypes that factories could produce. The exhibition lost money, but it drew wide attention in Germany and abroad.
