Sylvan by Johnson Bros. square serving bowl approx. 8x8 inches. Estate sale find. Has a dark spot inside and the underglaze on one side has a spot where someone got some blue on the white. It’s very rare to find this antique dinnerware at all, let alone flawless. Please feel free to contact me if you have any questions or need more photos. Thank you for your time. I will gladly combine shipping and have more of this pattern listed listed.
