Train to Lutz

A young man in a purple lobby boy uniform and hat looks upward with a concerned expression, followed by a man in a matching purple uniform with a bow tie who looks upward with wide eyes, then a man in a grey military uniform with "Cpl. F. Muller" on his chest looks downward with a serious expression, and the sequence repeats. The setting is the interior of a train car with wood-paneled walls and patterned red and beige seats.
