What is in this image? Be very specific. Scientific, Engineering style! No emotions, no opinions, no metaphors. Just the facts, as detailed as possible.

The image depicts a line drawing of two human figures. The bottom figure, an adult male, is carrying the top figure, a smaller child, on his shoulders. Both are facing forward.- The adult is drawn with features characteristic of a male human short hair, no visible facial hair, and a muscular build. He wears a collared shirt with rolled-up sleeves, belted trousers, and shoes.- The child sitting atop the adult''s shoulders exhibits features of a young human male short hair, a smiling face, and appears to be imitating airplane wings with arms extended horizontally.- The adult''s face expresses joy or amusement, characterized by wide eyes and a broad smile.- The clothing details include visible shirt cuffs, a belt with a buckle on the trousers, and fitted shoes. The adult''s shirt has four visible buttons.Both figures are outlined in black, and the image lacks color, shading, or gradient, indicating a minimalistic or cartoon-like drawing style. The proportions suggest a playful or whimsical interpretation rather than an anatomically accurate representation. The outline uses clear, confident lines with some variation in width, providing a dynamic quality to the figures. The image is presented on a plain white background, focusing attention solely on the figures.
