Malden was home to the National Company, a heavyweight in the manufacturing of radio equipment. The legacy of this enterprise and the town's distinctive place in radio history were immortalized in a unique piece of advertising - this world map centered on this otherwise little-known Massachusetts town.
<br><br>
This ingeniously designed cartographic promotional map was part of a strategy tailored to captivate the attention of amateur radio enthusiasts. It underscored the awe-inspiring power of radio communication, visualizing the potential of the most potent transmitters of the time. One glance at this map made it crystal clear: with the right equipment, you could quite literally tap into the global conversation.

A feature that makes the azimuthal projection stand out among other cartographic methods is its fidelity to directions. Any line drawn from the center point to another location on the map accurately represents the real-world direction. This attribute, where all points appear radially symmetrical around the center, makes it an invaluable tool in aeronautical charts.
