Copeland Blue Serving Bowl

Description

This is a blue serving bowl marked Copeland. It is embossed and stamped on the bottom. I was told that this was a flow blue piece, but I am not sure. I was unable to find another with this unusual pattern.
I am assuming this is pre 1970 when the name reverted back to Spode. It is a lovely bowl with no surface damage that I could find. However there is a manufacturing defect on the back under the glaze. It measures approx. 10" in diameter.
