Old carved wooden wall shelf

The shelf is in good condition. However you have to look at the pictures, there is a small piece of wood that is missing at the bottom, at the edge of the wood cut from the left post. Otherwise, no damage to report. It has a lot of charm, with this beautiful patina of waxed wood. The bottom shelf is the widest, 18 cm deep, 48 cm wide. The middle one is 15.5 cm deep by 48 cm wide. And the one at the top 12.5 cm by 48 cm wide. There is a 21 cm gap between the bottom shelf and the middle shelf, and 18 cm between the middle and the top shelf. It's probably a unique piece, made by a cabinetmaker, or a skilled handyman, at the beginning of the 20th century. Three original flat fasteners allow you to hang it on the wall, but you can also simply put it on a piece of furniture, or a console...
