Yes !! Each piece had 4 marks !! The Newcomb College mark, the decorators mark, the clay mixture, and the registration mark !! The article I posted is from the school archives !! Has the original marks as they were at that time !! If a line was drawn through the mark that would mean it was a “second” if the mark was obliterated,, it was unacceptable to the school !!
