Here is a vintage Canonsburg Pottery wheat pattern 14" oval platter. The pattern is not named, but it has golden amber wheat and blue flowers in the center. The platter has slight handles on the sides. It is 13 7/8" x 11 3/4." There is a small chip in the back rim, not visible from the front. The backstamp is gold and reads Allegheny Ware Canonsburg Pottery Co. Canonsburg, O Made in USA. The gold marks is a bit blurred and hard to read, but that is my best stab at it. This would blend well with other wheat pattern dishes.
