Old painting

Today I did some work on this nice old painting from Indonesia. It's about 50 years old. The paint is very thin. It almost looks as if the painting is painted directly on the canvas. Hardly or no underlayer. Otherwise I'd say it's in pretty good condition. Cleaning with a very soft swab and Turpentine oil didn't really leave much dirt on the swab. Amazing how clean a 50 year old painting can be. Not much else to do but find a way to stretch the canvas a bit as it's very loose. The frame has no adjustments and there are a few small scratches to fix. That's all. Good stuff!
