The picture identified as "The Kreutzer Sonata" at the "This Page" link by Jim Dixon doesn't come up by that title in any of my searches, but does come back as "The Kiss," which is the default filename for the image at that page. The site given appears to be the only one that refers to this picture (in the text) as "The Kreutzer Sonata."

Any search for "The Kiss" of course results only in Rodin, Klimt, and a whole bunch of wedding pictures.

I can't (without more effort than I'm willing to put into it) translate enough of the "Russian Site" to be sure, but it does appear to credit the image shown to Prinet. Enlarged as far as the available pixels permit, this image is done in very broad strokes, crudely (un)finished, and shows evidence of "adjustment" in body positions of the subjects. (The lady's hand on the piano, for example, shows a double image, probably an adjustment without complete overpainting of the original position.) It quite likely is a "Study for the K. S." if it is in fact done by Prinet. The only other Prinet painting I've found is a much more "finished" image - in typical 19th century realist fashion.

The Tabu ad, in the best image cited here, is almost "photographic," and has obviously been at least "touched up" to add the Tabu bottle that sits on the piano. My guess, based on present evidence, is that the Tabu ad was a photograph with actors posed "in the manner of the Kreutzer Sonata by Prinet," possibly with enough touchup to make it look "painterly." The picture in the ad is somewhat more "crisp" than the other example would indicate as the style of Prinet, although with the single sample found it's not possible to rule out the ad as a Prinet painting with the slight alteration of the Tabu bottle.

None of the search engines I consider reliable for work of this sort finds Prinet, but a couple of the less authoritative ones do report him as René Xavier Prinet, 1861 – 1946 (although one site did show him as born in 1540 and surviving until 17-something). A biography for one Bessie Davidson indicates: " In Paris, Davidson attended the Academie de la Grande Chaumiere, studying under Rene Prinet, and became influenced by his classical style." (It is not unusual for "impressively credentialed" artists of the late 19th and early 20th centuries to be omitted from art history resources. There were quite a few of them.)
