Founder of the great New York-based retail and design operation (1812-1902) that became legendary for its spectacular jewelry and decorative wares in metal, glass, and other materials. Rare 4.25 x 6.5 cabinet bust portrait of Tiffany captioned within the image, "Feby 15th 1892, My eightieth birthday," and floridly signed at the bottom of the image in ink, "C. L. Tiffany." Published by Sarony of New York. In fine condition, with light scuffing to the image. Tiffany is uncommon and desirable in any format, but signed photos are particularly scarce. Encapsulated in a PSA/DNA authentication holder.
