A "regular" customer that come to my garage sales keeps asking me to sell her this watercolor painting (she's one of those that isn't satisfied to just look at the items out for sale, she wants to see what inside the house). The outer dimensions of the wooden frame are 14.5 x 12.5". I hadn't even thought of selling it until she pestered me about it. I have no idea of it's value. The painting is entitled "Cove on Green River", but I can't find it or anything about this artist on the Internet. She is only interested in it because of the provenance - on the back is written where and when it was purchased and by whom. The next time she stops, what would be a reasonable price to quote to her?
