It’s often said that beauty comes from symmetry, but Paraguay’s flag is the exception that proves the rule—the asymmetrical Shannen Doherty or Owen Wilson of world flags. In the early 19th century, Paraguay displayed the Spanish arms on one side of its flag and the Asunción arms on the other side; today it continues the tradition by displaying the state arms on one side and a treasury seal (a lion guarding “the Cap of Liberty”) on the other. It’s the only national flag with a different design on each side.
