Along the way, Krushenick's work appeared in seminal midcentury group exhibitions at the Los Angeles County Museum of Art and the Art Gallery of Toronto in 1964; at New York's Whitney Museum of American Art and Museum of Modern Art, as well as Washington DC's Corcoran Gallery of Art, in 1965; at the Solomon R. Guggenheim Museum in 1966; and as part of the United States Pavilion at the 1967 World's Fair, a.k.a. Expo 67, held in Montreal, Canada. Despite finding acceptance at major institutions and inclusion among the most celebrated artists of the time, Krushenick viewed himself, with some satisfaction, as an outsider. As he told the curator and art historian Paul Cummings during an interview in 1968, critics and other observers have "never really pigeonholed me... Like I'm out in left field all by myself. And that's just where I want to stay."
