Unikat Boleslawiec Kalich SIGNED Poland 431 Cutting Board Trivet 5.75 “X 11” This is a beautiful example of this Polish Pottery line. It has a deep, cobalt blue border with brightly colored flowered in the center.   Below the stamped logo there is a signature that is hand signed on the back. I am not certain I am not sure I am reading it correctly, but it looks like GosiaS. The Cheese Board is in EXCELLENT condition. Any tiny flaws were made during its manufacturing.
