Classic French Illustration Style Prompt

Transform this image into a classic French illustration from the 1950s or 1960s. Use clean black ink lines with soft, controlled strokes, and apply flat, muted colors such as brick red, faded green, navy blue, or ochre. The style should feel elegant, simple, and slightly nostalgic, like an old European children's book. The background should be minimal or white, with a touch of urban or domestic charm - a café, classroom, street corner, or interior space. The overall mood should be refined, calm, and quietly expressive, capturing everyday life with gentle humor or poetic stillness. Inspired by artists like Sempé, Jean de Brunhoff, and André François.
