Cubist/Fauvist-style port scene table

A beautiful old marine painting with a cubist/fauvist port scene. Watercolor with traces of charcoal. Possibly saint tropez. Handcrafted paper on wood. Belgian or french school probably from the early 20th century. The monogram could not be identified. The painting was sold in an auction as being a work of the famous floris jespers, hence the sticker on the back. The monogram, however, is not known to this artist and therefore cannot be attributed to him. The paper stuck to the back of the plank is a little frayed at the edges (result of the exit of the frame). It is sold without a frame. Dimensions: 62 cm X 48 cm, 1.6 kg.
