A vintage mid century mixed media painting on canvas depicting an abstract expressionistic composition. Circa: 20th century. Framed. Abstract Expressionism became one of the most important art trends of the 20th century, emerging as a kind of response to the events of the Second World War. Abstract expressionism is a school of artists who paint quickly and on large canvases, using non-geometric strokes, large brushes, sometimes dripping paint onto the canvas, to fully reveal emotions. One of a kind artwork.
