Lot of 2 preparatory drawings for important Art Deco corsage brooches, probably by René-Sim Lacaze for Van Cleef & Arpels, in platinum, diamonds and emeralds, enhanced with onyx for one and turquoise for the other, formed by a barrette holding two mobile pendants, circa 1925/30. A similar model, attributed to Van Cleef & Arpels, was sold at HVMC on July 17, 2023, under lot 5.

Gouache and pencil on tracing paper (small stains, slight edge tears).
