Marked 1847 Rogers, a 1930s vintage silver plated flatware set for six in the Sylvia pattern, very deco. This is a luncheon set, six each of soup spoons, long handled grill forks and smaller salad forks, knives. Also a jam or sugar spoon and a butter knife.
It's all very tarnished, but I'd guess that it's never been used. The silver is smooth and even with no visible wear. It's a beautiful classic pattern in old International silver.
