This is a vintage-style illustration, likely from a children's book, rendered in black ink on a cream-colored background. It depicts two children playing in the water. The larger child, presumably an older brother or father, is lifting a smaller child into the air. Both are wearing traditional Japanese clothing. The larger child is wearing a patterned kimono with a square design and short pants. The smaller child is wearing a similar kimono with a circular pattern and shorts. Both are wearing geta, traditional Japanese wooden sandals. The larger child has a hat on his head. The water is indicated by wavy lines at the bottom of the image. Bubbles are scattered around the children, suggesting they are splashing and playing. The style is reminiscent of Japanese woodblock prints, with bold lines and flat areas of color. The overall impression is playful and charming.
