This Corningware piece is a mystery. It is white with brightly colored and labeled fruits: seville orange, plum, peach, and pear. The dish is 10 1/2" wide, 12 1/4" across the tab handles. It is not marked or signed, there are no Corning marks to be found. I know that Corning made some lines for other companies, but there are no marks for other companies, either. I also have not been able to identify the pattern name. It is in excellent condition with no chips or cracks.
