Persuasive map
A persuasive map is one that is designed to make a point, that is, to alter the viewers beliefs or perhaps even spur them to action. The archetypal use of persuasive maps is for the purpose of political propaganda, such as the “Gerrymander” map, but they can address a wide range of subjects. In fact, we have handled persuasive maps in diverse fields such as advertising,moral education,social science,anti-nuclear protest,women’s suffrage,tourism, and even oil fraud!
The techniques of the persuasive mapmaker are many and varied. To give just a handful of examples: Spatial distortion can emphasize the heights of mountains to make them appear more impressive for would-be tourists. Arresting imagery can create an indelible visual metaphor for an enemy or ally. Selective coloring can emphasize a threat or, for that matter, minimize it.
But a map need not necessarily distort reality to be persuasive. Consider this map from the Civil War era, which makes use of careful shading to suggest how the pervasiveness of slavery varied across Virginia’s counties.
A scarce volume of early American medical history. With an important article by Valentine Seaman featuring two all-but unknown thematic maps of yellow fever outbreaks in Manhattan, generally accepted as the earliest published epidemiological maps and preceding Snow’s work on cholera by half a century. The Medical Repository was the first American medical journal, founded […]
A striking 1943 poster depicting options for Allied offensives against the Axis, drawn by Robert M. Chapin for Time magazine. The poster features side-by-side maps of the European and Asia-Pacific Theatres on a stereographic projection, giving the viewer the sense of seeing the Earth from space. The theatres of war are, in a sense, carved […]
A 1996 imaginary map of the Earth after “The Tribulation”, as predicted by futurist, spiritualist and self-styled prophet Gordon-Michael Scallion (1942-?) This mammoth world map summarizes Scallion’s predictions and depicts their impact cartographically. The anticipated mayhem is predicted to begin with three “shifts” in the magnetic poles, each of six to eight degrees, expected to […]
A Communist Chinese propaganda poster featuring two persuasive maps of Vietnam and touting the supposed success of the Tet Offensive. Published in February 1968 during or just after the Offensive. Launched on January 30, 1968 by the Viet Cong and the North Vietnamese Army (NVA) acting in coordination, the Tet Offensive was a massive surprise […]
A spectacular albeit noxious French persuasive map using the octopus motif to promote anti-Semitism and anti-Freemasonry. As in other European nations, French anti-Semitism has a long history, most famously manifesting itself in the Dreyfus Affair of the 1890s and collaboration with Nazi deportation of Jews during the Second World War. In the public mind, Jews were […]
A striking, quirky and quite rare poster for the catastrophic 1972 presidential campaign of South Dakota Senator George McGovern. The 1972 campaign took place against the backdrop of the Vietnam War, ongoing cultural upheavals and the still-fresh memories of Kent State and the assassinations of two Kennedys and Martin Luther King. I was only five […]
A clever, striking and rather rare pairing of anti-malaria poster and pamphlet produced for members of the American military during World War II, illustrated by Theodore Geisel, aka Dr. Seuss. The Japanese conquest of Indonesia and the Philippines in early 1942 cut the Allies off from their supply of cinchona bark, which provides the […]
A striking poster published in the waning months of the Second World War, showing what was left of the Japanese Empire being decimated by American bombers attacking from three directions. The map is a much-enlarged version of one printed in the April 2, issue of Time magazine. Mapmaker Robert M. Chapin (fl. 1937-1970), Chief Cartographer […]
An imposing First World War Allied propaganda map highlighting the hegemonic nature of the Central Powers and arguing for a post-war reorganization of Europe according to the principle of national self-determination. The map depicts Europe and the Near East, color-coded to indicate the dominant nationalities in the vast region then controlled by the Central Powers of […]
An exuberant and entertaining 1926 persuasive map of the Eastern United States by the National Highways Association (NHA), touting construction “of a system of 250,000 miles of United States highways … to be built and forever maintained by the United States Government.” The map depicts the eastern section of a vast proposed national highway network, […]
