I listed this in my vintage shop yesterday.
It’s a walnut cheese board by Ernest Sohn. The flower tile is actually enameled copper and is so brilliant color wise. I wish the image was a match to the various dinnerware patterns that I collect because I would keep it.
Also – a learning experience. The signature on the reverse looks like Ernest John but the first letter is actually a stylized S, as I discovered as I found items online that still had their boxes.
