Here is a Vintage Wooden Large Empty FRAME, Medium Brown Color, Thin Edges, 17 1/8" x 21 1/8".
It is medium brown, medium oak color, with different hues of brown which gives it a very soft rich look. There are also small thin little darker ribs all over the wood, it comes from the quality of the wood itself.
The edges are thin and rounded, it has a soft touch, it has probably been sealed with some Shellac.
It is necessary to add a hook at the back to be able to hang it on a wall.
Size:
17 1/8" wide x 21 1/8" long x 9/16" deep
The wooden edges are 13/16" wide
It is possible to include an image, a painting or a photo at the back which measures:
16" x 20" x between 3/16" and 1/4" deep
The window at the front is: 15 1/2" wide x 19 1/2" long
Condition: I see a few scratches on the wood due to its age, some of the corners are not perfectly flush, but I managed to improve them with a soft hammer after taking the photos. Overall, very good vintage condition, please, check the photos as well. You will have to add a hook at the back to hang it on a wall.
