Vintage McCoy pottery shell dish, tray or bowl. c: 1967-74. Unique piece, but not sure what this was made for! It has the MCP in a pitcher symbol on the back with #901 USA. The MCP mark is shown in the McCoy books. It is 12 x 12 inches. It is a green blended glaze; some bits of blue. It has one itsy bitsy glaze pop or fleabite on one edge that doesn't show from the topside, see photo #4. Neat retro item! 1/20
