 Made out of concrete and ceramic, it is an abstract rendition of a woman's head and appears exactly how one would expect a Lichtenstein sculpture to be.Lichtenstein did not start experimenting with three-dimensional art until the late 1970s, and prior to this his main focus was on pop art.He mainly painted on large canvases and his paintings resembled comic-strip art; his signature use of bold primary colors, thick dark lines, thought bubbles containing context and sound effects, and dots used as a method of shading, can be seen in most of his works from 1961 and later, starting with his painting "Look Mickey".
