Nineteenth century painting HSP "Landscape with the river" signed + barbizon frame

Painting made in oil on wooden panel representing a landscape with trees. The work is signed (to be deciphered, presumably a beautiful hand). Beautiful state of conservation, the support is slightly veiled but almost imperceptible, a slight cleaning can be considered. The period frame of value is offered (some superficial retouching to consider). Support dimension: 18 / 36 cm, with frame: 34 / 52 cm.
