However, it still held on to many decadent bourgeois art forms such as Impressionism and Cubism.

Soviet Impressionism (1930-1980): painting, prints, works on paper. Soviet Impressionism began in the late 19th century when artists executed impressionistic techniques in defiance to Petersburg academism. It was similar to European impressionism in that their works remained colorful and dynamic. 

Spatialism (ca. 1946): all media. Spatialism refers to the art movement founded by Lucio Fontana in New York City around the time of Abstract Expressionism. It combined ideas from Dada, Tachism and Concrete Art. One of the most notable works of the Spatialism period was Fontana’s slashed canvases. 

Surrealism (1924-1940s): all media. This term refers to the movement founded by French writer André Breton. The aim of the surrealists was to discover the larger reality, or "surreality," that lay beyond tradition. Artists such as Dalí and Magritte were known for their surrealist paintings dominated by biomorphic forms.

Symbolism (1860s-1890s): painting, prints, works on paper. This movement refers to the late 19th-century movement in literature and art which focused on the world of ideas. The symbolists believed that art was the highest form of expression and knowledge. The movement rejected materialism and realism, emphasizing spirituality and imagination. Artists associated with this movement include Paul Gaugin, Gustave Moreau and Odilon Redon.

Tonalism (1880s-1900s): painting, prints, works on paper. Tonalism refers to the movement beginning in the 1880s, where artists painted landscapes with a tone of mist or atmosphere. George Inness and James McNeill Whistler were two of the well known tonal artists whose compositions featured dark, neutral colors such as gray, brown and blue.

Vintage Print: photography. Vintage photographs are typically printed by the photographer at the same time as the negative. A vintage print is usually higher in value than photographs printed later from the same negative.

Western Art: all media. Western art refers to all art depicting American Western life, such as cowboys, rodeos or country scenes. 

WPA Artists (1935-1943): all media. WPA stands for the Works Progress Administration, a government funded arts program with a section for artists. The artists in this group encompassed a wide variety of styles from figurative to academic to abstraction, and included almost every type of media. Artists included Milton Avery, Stuart Davis, Mark Rothko, Willem de Kooning and Jackson Pollock. The WPA was prominent until it was disbanded in the mid-1940s.
