This is one of many different sketches which I made, among some paintings, during my staying at the country, in a hilly zone of my country.
It is made on pastel special paper, with pastel colors and, in order to prevent erasing, it has a layer of blown fixative.
The drawing is already fixed with paper glue on a black pass-par-tout (a larger and thicker paper in proportional dimensions with the drawing), so that is ready to be framed. But if you prefer another color for the pass-par-tout, it can be removed and replaced.
However, for artistic reasons and for better keeping and transportation, I consider to be safer to reinforce the drawing this way.
