A rectangular public service announcement poster, framed in light beige, is affixed to a cream-colored interior wall panel of a Metro Taipei train car, located within New Taipei, Taiwan. The poster features the "Metro Taipei" logo in the upper left. Its primary message, in large Chinese characters "後背包請改用手提," is translated below as "Carry your backpack by hand to make space." The lower portion of the poster displays a colorful cartoon illustration against a background of faint, stylized outlines of human figures, representing a crowded environment. In the foreground, three anthropomorphic animals are depicted. On the left, a Shiba Inu wears an open, overflowing yellow backpack containing various items, including bottles and small cat figurines. In the center, a Corgi exhibits a distressed expression with an open mouth and raised paws, holding a small red handbag. A white speech bubble above the Corgi contains red Chinese characters "卡住了...", signifying "Stuck!" or "Jammed!". To the right, a grey cat is partially obscured by the Corgi, wearing a blue backpack with an attached yellow bottle. A smaller box on the right side of the poster contains Chinese text "禮讓出更多空間," which translates to "Be courteous and make more space." The surrounding environment consists of the train car's light beige interior, with a faint number "12" visible above the poster frame on the upper left. A dark vertical element, likely a window or door frame, is present on the right edge of the image. The scene is evenly illuminated by artificial overhead lighting.
