Painting has vintage oil landscape of Greek Ile de Santorini

Beautiful oil landscape of the island of santorini in greece. Painted by gérard détienne painter born in 1920 and died in 2003 from savoy. He painted a lot of landscapes of greece, I own one myself. I also have another very cubist canvas for sale from him. The work was made on a cardboard sheet, for framing you just order an american case that exists in 3 colors black and wood white for about 30 e on the internet, see last photo that shows the rendering once framed. I did not want to frame it myself because everyone will put the color that goes. The format is 10 f or 55 X 46 cm.
