This is a mid-century French powder compact likely purchased as a souvenir and features an illustration of the Sacré-Cœur Basilica in Paris. The body of the compact is metal, with a round 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 2.75"Dia x 0.5"H. Patination and surface wear are present. See images for details.
