This is a really beautiful mid-Century, French, quality print or reproduction of Claude Monet's renowned Impressionist painting 'Voilier au Petit Gennevilliers' of 1874.
This print has textural detail behind the glass frontage that makes it look as if it is an actual canvas.  It may even be a reproduction.  I cannot be sure without opening the back up. 
 
The painting depicts a calm evening scene with sailboats on the Seine at Petit-Gennevilliers.  Monet's brilliant skill with light and reflections is very much in evidence.  He used loose brushstrokes and a beautiful colour palette, typical of Impressionism. 
It has been framed in Paris with a slightly mottled silvery gold surround that compliments the colours perfectly.
