Though I am not a pottery expert, I did grow up in a home with a mother and step-father who loved art glass and pottery, and one of the pottery brands I remembered was Hull!. I searched and found a picture of the Hull logo of a capital 'H' inside of a circle!. Follow this link and it is the third picture down from the top!. I hope that helps and I hope it puts an end to your long search!Www@QuestionHome@Com
