Hi-
I googled the title of the item in quotation marks and added the word print outside of the marks. I found a CDV of your image and the owner of it said that the CDV came from a steel engraving. I then searched with the title in quotes and then the word steel engraving and I found a few. I think that is what you have but I am not 100% certain.
