Serpentine Antiques has dated this piece to the 1800s.
In any event, it is a lovely object mainly made of unblemished ivory having a wonderful patina, and trimmed with a design of gold roping, scrolls and garlands. The "souvenir" plaque to centre is gold, white and blue enamel, the whole overlying a red glass inset panel. It is extremely striking. The only flaw is one "v" shaped crack on top lid in left lower centre of glass. It is neither raised nor separated, and could be restored if desired. It is not detracting.

In the interior, the original mirror lines the inside of the lid, while the interior base is velvet lined.
Of generous size-3.75 inches long by 1.6 inches wide, by 1/2 inch deep.
Overall, it is a very rare object in very good condition.
