What an incredible example of the modernist movement in Mexico. This vintage 1950’s abstract modernist brass and glass tesserae mosaic tray was designed and handwrought by Salvador Teran. Salvador Teran was born in Taxco, Mexico. He worked in William Spratling’s Taller de Las Delicias but left there in 1939 to work with his cousins, Los Castillo, where he was responsible for many of their early designs. In 1952 he moved; settling in Mexico City and opening his own workshop. He also helped to start the shop, India Bonita: Plateria-Joyeria. This piece, sometimes called the “egg tray” is in good vintage condition. All the mosaic is intact and the brass maintains its original finish and patina. I have not cleaned the brass.
