Oil Painting Help - Signed Anderson

Hi,
I was given this painting and trying to find any information I can. The signature is really hard to see but is signed Anderson (no first name initial), located on the bottom left side. It is signed in brown paint. I Think the artist is Oscar Anderson but not 100% sure. The only other information i have is the frame size which I found on the back under the frame wood back, Size 24inchx36inch.
Any help would be so appreciated.

Thanks Kellz
