This is a drawing of a group of individuals sitting on a train as it approaches a tunnel. The image depicts a group of four individuals sitting in an open train car as they are about to enter a large and dark tunnel. The person at the front seems to be startled, while the others behind appear slightly anxious. They are dressed in formal attire, complete with top hats. Below them, visible through windows, more individuals are seated, also wearing formal hats and attire. The illustration is titled "L'entrée du grand tunnel d'un chemin de fer". The use of shading and line work effectively conveys the darkness of the tunnel and the contrasting lighter tones highlight the expressions on the passengers' faces. The drawing carries an air of anticipation and humor, capturing the experience of early railway travel.
