Corner wall shelf

Here is a small piece of furniture that is very practical for displaying a few small objects in a small space. This corner shelf is easy to hang on the wall because it is very light and has two hooks. It is made of solid (but thin) wood with turned wooden uprights. It must date from the 70s or 80s. It is in good general condition but does not hide some signs that testify to its past lives: small marks or light and very barely visible stains, the heads of the screws have corrosion and the three screws underneath are not identical. This shelf measures 36 cm in height, 22 cm on each side.
