Astonishing bold and simple, the flat background achieving a pure Pop effect and the beautiful modeling of the roan horse’s head made that much more striking by contrast. 1973, Amarillo, Texas. We wish we could see more of this painter’s work: Thelma Queen Collins (1897-1982). Oil and acrylic on board. Art measures 24 x 18, frame 29 1/2 x 23 1/2.
