Fabulous Sixties Abstract Oil Painting by Rita Robinson c.1961 Marbleized acrylic abstract painting on Masonite by gifted Sixties artist Rita Robinson. This painting will be the centerpiece of any room. A few spots of minor paint loss (see pics) and the dirty frame could use a bit of T.L.C. This is truly a fantastic mid modern find. Masonite dimensions 32" x 24". The frame measures 33" x 25".
