This is an antique 14 5/8" oval platter with a green transferware pattern around the rim. The green backstamp reads "Vitrified John Maddock & Sons England Burley & Co. Chicago." John Maddock & Sons used the Vitrified mark from 1880-1896. The Burley & Co supply company in Chicago imported pieces from John Maddock. Burley was in business from 1884-1917. I have not been able to identify the pattern name. The platter is in very good to excellent condition with no chips, cracks, or crazing, but there are utensil marks.
