Campbell's Pottery is sold in galleries and shops all over the country but the best way to buy it is to go to Bill Campbell's studio (a large, 2-story barn), filled with artwork in addition to his beautiful pottery. It is in NW PA, about 2 hours north of Pittsburgh off of I-79. His work really is beyond price and a work of art but it is very useful and practical. (I have the spiral baking dish and bowls).
