Well, if so, it will express the view that the first thing - a sketch , written by one of the "circle" Nicolas Lancret (Nicolas Lancret, 1690 - 1743). Perhaps someone from his students. Before him, in my opinion, does not hold. It is common in subjects with Lancret lunch outdoors at round tables and at the same time with the characters that are in some free poses, like those shown in your picture.
