Vintage Wall Hanging Wood Open Curio Shelf

Very good vintage condition. Wood shows various signs of wear and scratches that have been touched up with a walnut wood touch up pen. There is also some leftover glue residue from the previous owner that I have not personally tried to remove. Please see all photos for details. Handmade, signed on the back in German. Measures 20.25 x 16 x 2 inches. Shelves measure 1.75 inches deep.
