"It's a Small World" was the tagline of this very early airline poster advertising Pan Am's new long haul flight to Guatemala in 1938. Indeed, Pan Am changed the world by systematically solving most of the problems in intercontinental aviation single-handedly. Using brilliant pilots like Charles Lindbergh to pioneer routes to remote lands and test experimental aircraft, Pan Am became the first airline to begin rapid scheduled flights across the Pacific, Atlantic and throughout South and Central America in the late 1930s (at the astonishing cruise speed of 180 mph!). Pan Am chose a superb illustrator, Paul Lawler, to create a series of fine posters to build its brand and advertise all of these routes beginning in 1937. This image of the main church of Guatemala City (also known as the Metropolitan Cathedral) highlights the exotic experiences awaiting the lucky few who could afford to fly between continents.
