This painting is a wood panel oil painting. After doing so research, I believe it's an original signed Adriaen van Ostade from the 17th century. The condition is good, with colors still being vibrant. There appears to have some small cracks in the paint, which adds to the thought of its age. After looking at the back a bit closer, it looks like it has a wooden covering that has bubbled up, but the painting is very flat, so I think there is a protective wooden layer that was added when it had a new frame. If it would be helpful, I could try to remove the painting from the frame to see what the actual back of the painting looks like. Thanks!
