Animated marine painting "terrace by the sea" sailboats lighthouse hst/p

Interesting painting: marine, "terrace by the sea" made in oil on canvas mounted on rigid cardboard (original, cardboard), dating from the middle of the last century. Very nice atmosphere and good state of conservation, very slightly curved cardboard and the end of a folded angle (everything is visible in photos). Presence of a hypothetical signature in the lower center?, without certainty. Panel size: 46 / 55 cm (10f format).
