NEW YORK — Evoking glamour, power and a sense of adventure, posters touting trains and railways are one of the most notable subsets of collectible vintage travel posters. The streamlined shape of a train speeding through the night to its destination conjures up images of an impeccably stylish, gone-too-soon past as well as man’s mastery of machines and technology. While most railway travel posters depict a train, some poster designer instead choose to focus on alluring scenery or a legendary place.
