I purchased two of these lovely pieces of artwork from a woman who said they were Persian, hand painted on camel bone, and she had purchased them when she was young and lived overseas. In researching the artwork, I found some similar pieces. The descriptions state they are from Persia, hand painted Surat gari camel bone, watercolor paintings. and the frames were handmade Khatam marquetry.
From Wikipedia - Khatam is an ancient Persian technique of inlaying. It is a version of marquetry where art forms are made by decorating the surface of wooden articles with delicate pieces of wood, bone, and metal precisely cut intricated geometric patterns.
I have included several photos of the details in the frame, both from the front and the marquetry inlay on the out edge of the frame. Photos 4 & 5 show a closeup on the rich details in the painting.
This artwork has been very well cared for with one owner and is in great condition.
I believe photos 18, 19, 20 show the initials of the Artist as there are no other bushes like this on the painting, and some of the other artwork I came across during research stated the Artwork is signed. I am not pricing this an original signed piece of Artwork.
