A passing driver might not notice, but seen from above, this hillside in Belfort, France, seems to spring to life with this painting of a little girl.

Swiss artist Saype is known for spraying paint over wheat fields, hills and mountainsides to create realistic-looking portraits measuring several thousand sq m.

This particular work was created for this year's Les Eurockeennes, one of France's biggest music festivals, which takes place from Thursday to Sunday.

Saype's largest artwork - that of an old man smoking a pipe - was swathed across an area of 10,000 sq m between Lake Geneva and the Alps in 2016.

The artist, whose real name is Guillaume Legros, is a pioneer in the field of painting on grass. He is part of a contemporary art movement called LandArt, where artists use the framework and materials of nature in their work.

Sadly, his gigantic murals are as transient as the elements to which they are exposed to. His biodegradable paint - a base of linseed oil, water and flour, mixed with natural pigments - lasts only a month.
