THIS mind-blowing optical illusion is sure to test your eyesight—and your patience.
There are 16 animal and human faces hidden in this historical puzzle called The Puzzled Fox – but how many can you spot?
The cute forest scene features the cunning animal appearing to be climbing a tree while three eagle-eyed birds look on.
But camouflaged in the green, 12 other pairs of eyes secretly stare at you.
Don’t worry if you’re having trouble spotting any — the brainteaser has been baffling illusion lovers since US printers Currier and Ives produced it in 1872.
Now, almost 150 years later, The Puzzled Fox has reared its amazing head again to challenge a new audience.
It is extremely difficult for even the most keen illusion enthusiast to recognize all 16 faces.
In fact, however, the lonely fox is surrounded by other animal friends – including a horse, a lamb and a now-extinct passenger pigeon.
A sheep can also be seen at the base of the tree, while a wild boar lurks in the undergrowth.
A trio of human faces are also obscured by the tree trunk on the left, while two more adorn the tree on the right.
And there are a few more faces veiled by the forest floor to decipher.
The startling optical illusion had many viewers rubbing their eyes in fear after struggling to make out the hidden heads.
If you like racking your brains, try this brain teaser and see if you can spot the cat hidden in this image.
