Bonus Image Provenance: I commissioned Bacchus at ErosBlog to research this image further, and he has come up with the following additional details.

An early post of this image to Tumblr is here:

The image there is tagged “Donato Giancola” who turns out to be a science fiction and fantasy artist whose online presence is here:

http://www.donatoart.com/

That site includes several very nice galleries, including this one where your subject image can be found:

The art is called “Lethe” and it is a cover for a novel of the same name by Tricia Sullivan:

The oil on masonite original is shown as being for sale from the artist.

Some information about the book is available here along with an image of the art in cover form:

It is also available from various Amazon sellers:

Bacchus is actively taking image research commissions, and if you have adult imagery you’re curious to learn more about, I encourage you to visit Bacchus’s introductory post for his image-searching service, where you can find details about how to commission him.
