Vintage OB2 Ringed Mixing Bowl

Vintage 1950s "Over and Back" Ringed White Stoneware, middle size of three part nesting set, marked OB2. heavy white ribbed ironstone bowl. Perfect for serving, prep or accent decor. OB2 - 4 1/2" tall, has approx 9" diameter, and weighs 2 lb. 12 oz. prefer not to bundle due to shipping requirements, as item will be double boxed. tried photographing with and without flash for detail. flash creates a glassy appearance, but it's not like the newer pyrex or corelle bowls.
