The scene depicts a classic comic book illustration of the character Tintin, a young man with ginger hair, sitting at a table. He wears a yellow collared shirt and red tie, and is stirring a cup of tea. Beside him, his white wire fox terrier, Snowy, looks on with a cheerful expression. On the table, a bright red tray holds a blue teapot, a matching teacup, and a small bowl of sugar cubes. A thin, wavy line rises from the teacup to represent steam.
The setting is an interior room with a beige wall and a blue-framed window behind the characters. Outside the window, dark silhouettes of bamboo stalks are visible against a deep blue sky. A man with a stern, suspicious expression peers into the room from the bottom right corner of the window frame. A decorative blue and white patterned vase stands on a shelf or surface in the background to the left.
The artwork uses the clean-line style, characterized by bold, flat blocks of color, strong outlines, and minimal shading. The color palette is composed of primary and secondary hues, including the vibrant red of the tray and tie, the sunny yellow of the shirt, and various shades of blue used for the teapot, window, and accents. The composition is balanced, with the main characters framed by the table in the foreground and the window in the background, creating a sense of narrative tension between the peaceful tea time and the intruder outside.
