Definitely French. I've seen quite a few of these in France. I've always believed they were made as a promotional item, the man's head may be a trademark or similar used by a company.
As to maker, definitely not Jobling or Lalique. It doesn't appear in P. Decelle's Sabino Maitre Verrier de L'Art Deco 1878-1961 Catalogue Raisonne so most likely not Sabino. Etling were a retailer, not a manufacturer. Most of their glass is believed to have been made by Choisy-le-Roi. I wouldn't rule out Choisy-le-Roi as the maker, though equally it could well be by another producer.
I would think the best course of action is to look into the man's head design and see if you could match it to a company. A lot of promotional pieces of this type seem to have been made for Vineyards or for restaurants, so that may be a starting point, particularly given the grapevine pattern on the bowl.
