During the Washington years, 1969 to 1978, Protetch represented Andy Warhol and other Pop artists; gave Vito Acconci his first one-person show; and was showing Conceptual artists such as Sol LeWitt, Joseph Kosuth, On Kawara, Robert Berry, and Doug Hubler as early as 1970. Kosuth and Art Language Press Group also had one-person shows during those years. Protetch presented early performance art by Dan Graham and Dennis Oppenheim. Donald Judd, Sol LeWitt, Dan Flavin, Joel Shapiro, Jo Baer, Lawrence Weiner, and Carl Andre exhibited. The Gallery mounted several political shows, including the group show 'Political Art' which featured Dorothea Rockburne, Daniel Buren, Sol LeWitt, Carl Andre, and Robert Morris. This show was unique in dealing with the Marxist and political/economic involvements of Minimal and Conceptual art.
