This solid copper oval dish or bowl isn't marked but I believe it dates to the 1940s or 1950s - it has a nice Mid Century Modern biomorphic look. It's 8-3/4 by 5 inches, standing about 1-1/2" high on four copper ball feet. The sloping sides are scalloped with a convex bubble design around the rim. There are a few light marks to the finish and small patches of lighter patina in the bottom, no doubt from something displayed in the center for many years.
