Just a bit of information....many people paint pictures of places that they have never seen/visited but have seen pictures of. The market today is flooded with French decorative items that are selling right and left reinforcing this.
If you take an art class, they have you paint samples from different periods in time. Doesn't make their items that old.
The back of yours doesn't look that old (100 years).
the style is reminiscent of those sold in 40's to 50's.
