From the German/Frenchfolk art tradition of decorative wooden hanging harvest/bread plates, this mid-century piece was made some time between the 1940's and 70's. It features a nice wood grain, over which the swirls of wheat dance, symbolizing abundance, prosperity, and the harvest. Nice edge design with carved scallops into the wood.
Not signed, but it does have a nice sturdy hanger so it's ready for your wall. 7.33" in diameter.
