Optical illusions

Having now looked into many optical illusions and many intruiging images, I have decided that I will attempt to create an image featuring the same concept of seeing two different images in one picture.
Some of the optical illusions found in my research can be seen below...

A mix of old and young.

An elderly couple/two men, one playing guitar, and a woman approaching from an archway behind

The face of a man with a moustache and large hair/Two men on a horse, surrounded by other characters, including the beasts they must slay

A human skull/A man and woman sitting at a table with a bottle on ice
