Wall shelf silver patina bronze glass early 20th century

Brass wall shelf with silver patina. French work, early 20th century. The bronze-toned beveled tempered glass shelf is not original (probably a replacement in the 1980s for the original glass shelf). Very good overall condition. Note some discreet wear marks on the glass. These marks are not visible when the glass is placed on the metal structure (see photos and zoom). The total width of the shelf is 63.3 cm. The usable width of the glass is 60.3 cm. The total height of the shelf is 8 cm and its total depth is 15 cm.
