Attributed to Wojcieck Voy Fangor, Polish, American, 1922 to 2015, oil crayon painting on paper depicting an abstract composition, 1969. Signed and dated, lower right. Framed. Wojcieck Fangor is known for Abstract illusion and optical art painting, social realism, posters. Mr. Fangor, who was known for his blurred circles, amoebas and cloud shapes in dense, saturated colors that seemed to throb and swirl, first became known in the United States in the 1960s, when his work was included in two group exhibitions at the Museum of Modern Art in New York. In 1970, he had a one man show at the Guggenheim Museum. His work, perched midway between Color Field painting and Op Art, dazzled critics, notably John Canaday of The New York Times, who reviewed the work in rapturous tones. One of a kind artwork.
