Art Naïf. Wien festival. Mid-century painting from 1960’s

Art Naif. 
Painting from 1960s.
Wine festival.

Dimensions: cm 81 x 59
The painting represents a cheerful popular scene with a musical band, people dancing, a man pouring wine from wooden barrels, tables full of colorfully dressed people.
A childish and naive vision of the world, with a highly studied decorative effect.
Indeed, despite being apparently simple, it has a construction/composition with a studied modified, unreal perspective. Technique: oil on canvas.
Under the color you can see the underlying design in some places. In good condition. Original frame.
