Imaginary Field. Acrylic on Styrofoam, About 22x33, 7/14/19

My sister asked me to paint something on this piece of pink styrofoam that she puts in her window to block the noise from the neighbors. She grabbed it before I finished it. I did not measure it. I asked her to measure it and she told me it measured 33x33. This is a rectangle, so if one edge is 33" the other edge is probably 22".
