McArthur Map-card - 10-pack, 25-pack, or 100-pack
Putting Australia at the top half of a map, as was done in McArthur's Universal Corrective Map (1979), may seem like the work of some prankster in the Outback, but in fact, there is no intrinsic reason to put the Southern Hemisphere at the bottom. Nor is there a universal mandate that requires the "Prime Meridian" to pass through Greenwich, England. Instead, these are choices based on mapmakers' objectives and biases. Like other choices in mapping, they show how individuals in a particular time and place perceived their world.
