I would love to help. Please add a photo of the painting (straight on, not at an angle, no flash) and one of the signature. In this photo, the signature is covered by the date stamp. I would also like one picture of the back of the painting as there may be some visual clues there( like type of nails and canvas used).You can add pictures by using the paper clip icon or ADD FILES button. These features work best on a desktop computer. I t may seem like the pictures are not attaching, but I will let you know if I don't get them and we can use another option.
