This is a vintage 1940s J.V. Pilcher brass compact.
The brass compact features a black map of California on the lid and is leakproof. Inside is a white powder puff with the original paper still attached, and a mirror.
This compact measures about 3 1/2" long, 2 3/8" wide, and 3/8" deep.
It is in good pre-owned and unused condition in the original box, but the mirror has some crazing.
