July, August, September 1969 was an exhibition organized by Seth Siegelaub consisting of works by eleven artists at eleven separate geographical locations. The trilingual catalogue—in English, French, and German—both documented and reproduced the diverse works, which ranged from fleeting events and performances to museum shows and open-ended environmental interventions. In each case, the respective artist was responsible for providing information on the work’s materials and design.
