European school (XX) - Paysage de provence

Purchasing this artisanal painting, acrylic/oil technique with knife and visible impasto, on a linen canvas mounted on a keyed wooden frame with a crossbar (studio quality), from a flea market in a small town in the 94, I think it's the work of a local artist from the south of France, apparently from the late 70s or 80s.

According to my research, the canvas resembles a known artist, HELENE GASTIN MOZOL, same landscape but seen from behind.

Style: Provençal school, post-impressionism.

On the frame, upon closer inspection, letters and numbers appear.
