artaria & co. oval napoleon print in frame

I was told that Artaria & co. were the producers of classical composers, including beethoven, Handel, etc., and that this print was most likely a promotional gift to celebrate the release of a new symphony of some sort. I was told that it is very attractive. It looks to be charcoal maybe, and watercolor, or pastel. The charcoal sketch is unfinished towards the bottom of napoleons torso, and it is only colored down to about his lapels.
