This handsome American sterling repousse child's mug or cup was made by Tiffany & Co. The mug features a wonderful foliate design; even the scrolls at the top of the design suggest tightly closed fern fronds. The Tiffany mark, "M" on the bottom dates it between 1875 and 1891, following the Tiffany tradition of adding the surname initial of the President of the company to the marks. During the period this mug was made, Edward Moore was the President. 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 fine mug would make a fine baby gift or present for a young child--truly a heirloom gift.
