You have 20/20 vision if you can spot all the faces in this optical illusion in five seconds or less
IF you can spot all the faces in this optical illusion in five seconds or less, you just might have perfect vision - can you do it?
Not everyone can scope out all of the faces hidden in the sprawling tree.
Most people can only find two of three faces only to find out there are actually ten within the image.
Called the "National Leaders Tree," the image is said to include the faces of famous figures such as former British Prime Minister Margaret Thatcher and ex-Soviet leader Mikhail Gorbachev.
However, who the drawings are meant to depict has been the subject of debate for a long time.
Some have argued that the drawing dates back to 1880 for Harper's Illustrated, making it unlikely that any of those leaders are shown.
Looking closely, you will see the ten faces etched into the tree's branches, surrounding its stump.
Some are facing one another while others are looking away.
If you've already solved the illusion, you might want to try your hand at finding Mario in this Where's Waldo-inspired brain teaser.
There are flocks of people outside, dancing on cars, hugging in the corner, walking through a market, and sitting down to eat together at a table.
