Artiste inconnu (Collection Florin Stratinovici) - Le retour à la maison

Very beautiful watercolour on thick paper glued on a 20th century cardboard. The painting should be a study because we can notice pencil traces in the center of the board.
The work is registered in a private collection.
No follow-up is available at the moment, but I am sure that this proof can be the subject of an interesting study (period before Picasso's Cubism).
