Oil on canvas abstract painting, signed and attr. Jack Tworkov (American, 1900-1982) on lower right corner. 15.5 x 11.5 inch (39.37 x 29.21 cm). An early member of the New York School and a first-generation Abstract Expressionist, Jack Tworkov painted with gestural brushstrokes, emphasizing texture and line. His most characteristic work contains flashes of color against muted, monochromatic backgrounds, documenting his gestures and drawing attention to pigment and medium. In the second phase of his career, he abandoned his expressionistic practice for a more theoretical one and began to employ grid-like structures, geometric patterns, and other elements of Minimalism, although often deliberately damaging and deteriorating his paintings.
