This striking One Patch Checkerboard quilt has strong visual impact due to the size of the blocks and the use of solid colors. Each block is 1 1/2 inches to a side. There are a total of 1764 blocks which give something of an op art effect. The triple borders are quilted with alternating cable and criss cross patterns. The quilt is in pristine, unwashed condition. Measurements are 80 inches square. Pennsylvania origin; made 1920's.
