Watercolor painting circa 1870 "The conversation" signed with Marie Louise

Beautiful watercolor, circa 1870, presented in his marie louise of the period. The work is signed (bottom left) but unfortunately illegible. Excellent workmanship, very good condition for a work of this age, sold with frame cardboard but without glass, too risky... Dimension of the view: 11 / 19.5 cm, with mayor louise: 20 / 28 cm.
