Rembrandt print information
I have purchased an old print, the paper is obviously old, the ink of the picture is very different froma signature and what I think is a print mark. I spent hours online, found this mark only 2 other times, and reference to this picture only once-even when I searched by title specifically. Also, the print is numbered. I got the print several years ago and have since forgotten exactly where and for how much-it did not come with a certificate-nor was it advertised as a Rembrandt. How can I locate more information that I am sure can be trusted and at the same time be discrete?
Thanks
