Vintage french oil painting on board in naive style, signed

Vintage french oil on panel in naive style, signed but I can't read the name. The simple and naive style of this painting gives it a special strength, almost like the honesty of a child's clean gaze. It transports us to childhood, to the happiness of those summers in which the greatest happiness was riding a donkey and running free in the countryside. It's in good vintage condition, just the frame is a bit damage. It measures with the frame 40 cm high and 48 cm wide and 4 cm deep. Without the frame it's 36 cm wide and 29 cm high.
