Children walking with flag and group in background

Photograph of an event. In the foreground, three children are walking along a path: a boy in a light shirt and dark trousers is carrying a flag, a girl and a boy in school uniforms are walking beside him. In the background, a large group of children in school uniforms is standing on a lawn near a line of trees, many of them raising their right hand to their head. On the left, two posters with images are visible.
