Antique Miniature Oil Painting - 19th or 20th Century Landscape Painting - Oil On Canvas with Wood Frame a€“ 4 by 6 inches - Unsigned I believe this small painting of a group of cows near a bridge is from the late 1800s or early 1900a€?s. The detail on this tiny piece of canvas is quite remarkable. The oil painting measures 4 by 6 inches. I don't see any paint loss or damage to the surface. It is unsigned. The gold color decorative frame is in very good condition with light abrasion to the edges. It measures 4 ?? by 6 ?? inches.
