Hi have a small looks like oil painting and needs a very good clean as dirty also the frame looks original, the picture looks like a mother and daughter
18th 19th century over looking a lake with trees either side and a castle in the distance. Have found a mark it says Bossi..cant quite read the first initial.
Very nice picture has anyone any ideas as im having no luck.
Would be most grateful
Kind regards
Andrew
