Description : I have an old painting at home. I don't want to take him somewhere to the second-hand bookstore, because the friend was cheated on like that. Can't send a photo of the image somewhere and find out what it's worth? I mean something proven where he understands. An auction house or something.
Last Answer : I have no personal experience, but I would try to contact a couple of companies / appraisers from: https://www.google.com/#q=odhad+image
