Fantastic Vintage Oil On Board Landscape Van Gogh Style 1960s/70s Retro.
This is a truly remarkable oil on board landscape, the quality is exceptional. 
The subject is stunning and the artists skill is clear for all to see. A real standout piece.
In my opinion, considering the age and frame, this is from the 60s or 70s. 
This is a lovely thing, that looks even better in the flesh. 
Initialled D M and influenced heavily by the style of Van Gogh. 
Measurements of frame are 49cmx39cm.
