This is a enamel guilloche compact from the 20s. It is marked "PLATE SILVER" on the bottom and has very pretty blue enamel guilloche on the top. There is a finger ring attached to it by a chain to keep that dancing flapper girl from loosing it.
The compact is in good condition for its age. The guilloche is perfect. The plate silver is very worn. The mirror inside shows a little bit of wear to the outside edge. Also, the chain links are bent. The compact measures approx. 1.5 inches in diameter and 7/16 inch tall. The chain is 3 inches long.
