If it was from Vivid it's probably also from the set of one of the movies she was in. From my vague recollection of their photosets of the time Vivid seemed to rarely do any photosets at all that weren't also involved with a movie they were working on. At least I can't think of any. Really the small photosets were more promotional material for their movies than anything. It makes me wonder why they would leave a potential revenue stream like that on the table, other than at some point they morphed from one of the best producers of the industry as far as production value was concerned and turned into a crappy company. Now they don't really exist any more.
I'm not super familar with Ray, although I know he did stuff for her and they had a relationship so I can't make any value judgements on him as a person. In any case at one point Nina was legit one of the most attractive people in the industry's history, especially at the very beginning of her career, and it makes me wonder how things would have turned out if she worked with better people in a bussines sense not only from the beginning, but even more so after leaving Vivid.
