SFAM set of 4 Art Deco silver-plated teaspoons in Printania style

This set of 4 teaspoons is an Art Deco model, similar to the Printania by Christofle. They are antique dessert or coffee spoons. Made of silver-plated metal, they come from the silversmith house SFAM "Société Française des Arts Ménagers". In generally good condition, they show signs of use with scratches and some oxidation. Notably, there is wear to the silver plating on the back. These spoons measure 14 cm in length. They are stamped "SFAM", "Métal Blanc", and "18gr" for the silver weight used.
