The underside of the piece is stamped with the Tiffany & Co. maker's mark, sterling 925-1000 and the initial 'M' for the company director between 1907-1947, John C. Moore II. The bowl is in good overall condition. There have been one or two dents professionally removed, but this is hard to notice without careful inspection. The bowl is somewhat off kilter, when viewed from certain angles, particularly when it's viewed directly at eye-level. However, this is not very noticeable with normal display. The bowl weighs 458 grams or 16.2 regular ounces.
