Framed vintage original oil painting

Very nice vintage oil painting. A seascape, of a lighthouse overlooking a rocky jetty. This piece has an impressionistic feel to it, since everything seems to blend together a little. There are many different shades of blue and the cumulus clouds are bright and shining over the sea.
This is framed in a beautiful wooden etched frame which no doubt has some value..
It is in excellent condition, the only imperfection being a small black pin sized dot towards the middle which doesn''t seem to belong there, but I''m sure could be easily fixed
