Vintage made in Italy Stix Baer and Fuller purse

Vintage made in Italy Stix Baer and Fuller purse. A beautiful vintage piece, this crossbody or shoulder bag has a longer knotted strap, a scalloped top edge, button pocket and zippered pocket. Outside has some mars on it (feels like leather, no tag inside that I can find), see pictures. Color is hard to capture adequately in pictures, it’s a tan/taupe/gray.
