1970s vintage stoneware pottery goblets, set of six wine glasses in original box Cedarburg Wisconsin

Hippie vintage hand thrown pottery goblets, a set of six still in the wood presentation case from Stone Mill Winery, Cedarburg Wisconsin. The box is worn and a bit broken at the corner, but the goblets look great (one has what I think is a makers flaw but might be a chip as the foot). The goblets measure about 4" tall, 3 3/4" across the rim.
