Outstanding group of four rare hunting lodge chairs designed by Biermann Werner for Arte Sano. The chairs are made of hand-tanned cognac colored leather. The stout wood frames are crafted from solid white walnut wood. White leather chording binds the leather with decorative and functional stitching. There is no mystery to the provenance. A gold foil label beneath the chairs indicates the maker, material and origin. Made by Biermann and Cia Inc. in Bogota, Colombia. These chairs are 100% original and are being sold as-is in worn condition. A few of the seats have torn leather. These are project chairs, in need of restoration.
