Moving to Los Angeles in 1956, Ed Ruscha came to prominence there in the late 1950s when he began making small collages similar to those of Jasper Johns and Robert Rauschenberg. Soon he began to refine his collages, isolating and recombining words and images in increasingly subtle and unique ways. Because he drew upon sources from the real world and embraced the vulgar techniques and imagery of commercial culture, his work is associated with pop art. However, unlike some pop painters, Ruscha seldom seemed to be making art about other art. Ruscha used unconventional materials in his graphic work of the late 1960s and 1970s: He drew with gunpowder and painted and printed with foodstuffs and with a variety of organic substances such as blood and the medicine Pepto-Bismol. He was well known for his depiction of words and phrases (e.g., Three Darvons and Two Valiums, Very Angry People, He Enjoys the Co. of Women) and for the books he published of his series of deadpan photographs, including Twentysix Gasoline Stations (1962), Some Los Angeles Apartments (1965) and Thirtyfour Parking Lots in Los Angeles (1967). Such work was influential for the development of conceptual art, although Ruscha’s pieces have a characteristic low-key humor.
