Thank you for submitting your painting for appraisal. The artwork is apparently a copy after a winterlandscape painted by Georges Charles Robin (1903-2003) who was a renown landscape painter. One can assume that his son (?) Michel Robin (1928-?) copied the painting with permission of his father (?). The painting is fully signed "Michel Robin" and titled "HIVER A ROINVILLE". Few paintings by Michel Robin were sold at auction. The estimate is based on the few results. I hope the information provided was helpful to you.
