Gibson Rainbow Stripes Platter

Red, yellow, green and blue band platter measuring 12 1/4 x 8 3/4 inches. It is marked as handpainted. There are no chips, cracks, breaks or rough rim, but has light utensil wear and one tiny dot of loss of paint to red band. This looks more like a miss from the factory than any usage wear. I need your zip code to calculate the postage.
