Sanor Ceramica Covered Pie Plate - Made in Portugal

This is a vintage Sanor Ceramica Ceramic Covered Pie Plate - Made in Portugal. This is circa 1970s and is a substantial dish and weighs over 5 lbs. This is vintage and I think in great condition. 2 blue marks are shown on the side that are part of the original making of this plate, which are from the blueberry color in the middle and a slight wear on the red of the strawberry on top in the middle. No cracks, chips, or other issues that I can see. Measurements: Approximately 10" W x 5.5" H
