Impressionist painting "Shepherd and his sheep" 19th century signed Barbizon

Old painting made in oil on wooden panel representing a landscape with a shepherd and his flock of sheep on the edge of a wood. Signed but to be deciphered. Good state of conservation but cleaning the varnish could undeniably bring additional luminosity to this work, the frame with period roses (re-gilding) is offered with it. Panel size: 23/33 cm, with frame: 40/48 cm.
