We don't know since we have not actually seen a painting by Nell Dimon. This oil painting measures 30 inches high by 40 inches across and with the frame about 31 inches by 41 inches. The painting is signed Dimon in the lower right corner and dated 57 for 1957. The painting looks like it is signed Dinon but the first N is an M. There is also a framer's label on the back from a Mill Valley , California company.As for condition there are several areas of paint cracking. There are a couple of paint chips. You can also see faint lines from the stretcher on all four sides. There is also some minor restoration to the paint located in the edge of the lower right corner but pretty well done. This painting has a great Mid Century look to it. The item "OLD California Artist Fine Art ABSTRACT OIL PAINTING Mid Century Modern artwork" is in sale since Thursday, December 6, 2018.
