Pencil drawing of the market of la rochelle late 19th early 20th

Pencil drawing, by an architect certainly. Drawing bought in la rochelle, perhaps representing a square in la rochelle. A provincial market in any case whose tents and awnings are recognized in the sun. Nervous line, in vertical stripes denoting rather the professionalism of an architect than the inspiration of a painter. Unsigned, undated. Damaged but beautiful and old, see photos. Frame dimensions: 20x28.5 cm drawing dimensions: 15.5x23.5 cm. Framed, ready to hang.
