Composition in blue tones, earthy, red ochre, black and white. Contour lines, some shaded and scraped. Boy with vane occupying almost the entire area of the support against a plain background. The boy is from the front, slightly turned to the left, wears blue long sleeve shirt and pants and is barefoot. Arm bent forward and on the right, holding in his hand a wind vane that suggests being beaten by the wind; on the left straight up. Legs too far apart, and the on the right is far ahead than the on the left, suggesting that the boy is taking a big step.
