Individual or personal ashtrays like this were widely used at 1950s ladies' bridge clubs and luncheons. This set of four porcelain ceramic oval biomorphic shape stacking ash trays is decorated with violets and trimmed in gold. They're about 3-3/4 by 2-1/2 inches each. Each has a foil Made In Japan label on the bottom. All four are clean and in excellent condition with no damage or wear.
