From the Cornell University Library, via the Facebook page of Phi Alpha Theta, a collection of “persuasive maps”:
This is a collection of “persuasive” cartography: more than 800 maps intended primarily to influence opinions or beliefs – to send a message – rather than to communicate geographic information. The collection reflects a variety of persuasive tools , including allegorical, satirical and pictorial mapping; selective inclusion; unusual use of projections, color, graphics and text; and intentional deception. Maps in the collection address a wide range of messages: religious, political, military, commercial, moral and social.
