I have a oil painting on canvas of a lighthouse and can't findout who the artist is..
It looks like the name starts with ARR but the rest of the signature is faded and can't find any information about it.. it's 3x4 foot wall painting.. any information would be greatly appreciated.. thanks in advance.

Have you checked eBay?

Please post a photo or two.

A photo of the painting and a close up of the signature would really help us help you. There are so many paintings, many lighthouse paintings, and many artists that aren't famous enough or well known enough to be virtually impossible to find unless you find someone that knows their work. But posting a picture may help us find more info for you. Without a photo I'm afraid we're as helpless as you are to find out more.
