Offered for sale to organize my collection. It is a wooden frame. Approximate size: Height: 20.5cm Width: 53.5cm Depth: 3cm The window size is large enough to display a postcard. How about using it to display small paintings? It has a nice amount of paint staining, giving it a very good look(^^) Perfect for painters, those who like vintage furniture, and retro interiors!
