This is a Homer Laughlin, Coventry, Casualstone, 12″ round meat platter.
These pieces were all produced around 1970 by the Homer Laughlin Co., for Coventry, who then distributed them as their own. They were made using the Homer Laughlin, Fiesta, molds. There were a few original pieces added to this pattern, but for the most part, including the antique gold color, they are the same as HL Fiesta.
This platter is in very good, used condition. Take a look at the photos, and if you have questions, please e-mail.
