This pair of porcelain trays was produced in the U.S.A. in the 1890s. We believe they were made by Ott & Brewer. There is no identifying mark. They measure 8 1/2 inches square and are 1 1/4 inches deep. The plate of the woman is marked Marie Stuart and the man is Frederick Henry. The porcelain is extremely thin and fragile with an ivory hue. The rims of the trays are ruffled and curly and there are four button feet on the bottom of each one. The portraits are expertly hand painted with intricate detail. Viewed with a magnifying glass, the brush strokes are extremely fine. The lace on their costumes is enameled so that you can actually feel it. The gilded borders and ornamentation are accented in raised gold. This pair is truly exquisite. These trays are for a connoisseur of antique porcelain. Both trays are in excellent condition.
