This 1930's Art Deco Porte-Clés by Jean Boris Lacroix showcases his skill in transforming industrial materials into luxurious objects. Featuring an architectural glass pocket dish with a nickel-plated metal wing frame, it embodies Lacroix's modernist and Cubist sensibilities. The strict geometric design is a hallmark of his work, finished with the artist’s monogram stamped on the metal base.
