THERE is more to this image than first meets the eye – more women, to be specific.

Ukrainian artist Oleg Shupliak specializes in creating mind-boggling optical illusions that feature portraits with hidden images.

In one of his most popular drawings, viewers immediately see a young woman who appears to be talking on the phone.

How many other women can you see in the image?

Only a minority of people can find all four women in the drawing in less than 20 seconds.

Upon looking closer at the central woman’s cheek and hands, the face of the second woman can be seen near her palm.

It is more difficult to find the third woman.

Zooming into the woman’s arm that is holding the phone, careful viewers will see a pair of eyes, a nose and a mouth.

The third woman’s face is in profile and looking off to the side calmly.

The fourth woman is hiding in plain sight.

Look at the stomach of the original woman and you will see a big pair of lips and then the eyes of the final woman.

Fans can head to Shupliak’s website for a close-up version of the image.

Shupliak is well-known for his drawings and the interesting perspectives they provide.

Some of his work is used to interpret personality or teach people something about themselves.

One popular image from 2012, “Genius and Madness”, asked viewers to consider the meaning of the two states and what they understood about them by seeing his work.

Another set of his paintings challenged viewers to find up to five faces in each optical illusion.
