[1] New York School Abstract Expressionism, represented by Jackson Pollock, Willem de Kooning, Franz Kline, Robert Motherwell, John Ferren, Marca-Relli and others became a leading art movement of the postwar era.

And a year later he opened his own studio in New York and managed to earn an income by teaching and producing occasional illustrations for the daily and weekly press.

[4] He lived and worked in many countries around the world, eventually settling in Parma, Italy with his wife, Anita Gibson, whom he married in 1951.

[15] Marca-Relli's early cityscapes, still lifes, circus themes and architectural motifs are reminiscent of Italian surrealist painter Giorgio de Chirico.

He combined oil painting and collage, employing intense colors, broken surfaces and expressionistic spattering.

Over the years the collages developed an abstract simplicity, evidenced by black or somber colors and rectangular shapes isolated against a neutral backdrop.
