This handsome American sterling repousse child's mug was made by Tiffany. The Tiffany mark on the bottom dates it between 1875 and 1891. The mug or cup is 3.5 inches tall and 2.75 inches in diameter. It is very heavy, weighing 6.5 ounces on a postal scale. The work is exquisite and the piece is in outstanding condition. This handsome mug would make a fine baby gift--truly a heirloom gift.
