This is a mid-century Italian powder compact likely purchased as a souvenir and features an illustration of the Basilica di S. Marco in Venice. The body of the compact is embossed vinyl, with a mirror inside the lid. The powder is long used, but the piece is sweet and vintage makeup collectors would likely find this piece very unique.
Measures 3.5"L x 2.75"W x 0.5"H. Patination and surface wear are present. See images for details. Found in France.
