It would have been quite nice if you'd clarified what your interest in the painting is, Maxfrost, other than re just some trifling curiosity. It is curious that whatever you've seen (that you couldn't identify) didn't include artist details, though, when it was sold ostensibly signed.
But I did just look it up for you and it ostensibly fetched 5630 Euros on 29th Apr 2013 at a specialist "Femmes a tout prix" sale at the Hotel Drouot.
The Mutualart info, per helpfully posted above, quotes a different June 29th sale, which is odd. I don't have access behind that firewall to see what the other auction details are. It might be a mistake re the month or it might be that the painting was either oddly sold on again somewhere else damagingly quickly for some (unlikely good) reason, or there was a problem with the earlier sale and it either wasn't paid for or was returned.
