Antique lampshade in leather

Superb lampshade made from animal bladder (pig or calf) probably from the 1930s to 1950s. Of course, due to its age, it shows signs of wear, but its seams are intact and the designs are clearly visible. The edges are made of brass wire and are in good condition. However, there is a tear and a small dent (see photo). It has been cleaned and treated with linseed oil, which enhances its brightness remarkably. Exact dimensions available upon request. Very careful shipping; we are experienced in sending fragile items (glass, mother-of-pearl, etc.).
