Watercolour outlet 1960

Very nice watercolour with amazing colours between green and orange .
One can guess a landscape with mountain and bushes under a stormy sky.
In fact it is at the limit of an abstract painting.
It is signed at the bottom right but the signature is undecipherable .
In the left corner one can see a dedication to: « monsieur Durieux with all my sympathy »
In outlet very good condition of use
It has a natural wood frame.
