The Optical Illusion That Makes Us Look Twice

Look closely at the image. What do you notice first?

Perhaps you see a young woman turning her face away, her dark hair tucked beneath an elaborate hat. A pale veil falls behind her head, and a dark, textured garment surrounds her shoulders. Only part of her face is visible, giving the portrait the appearance of a woman glancing into the distance.

Or perhaps an older woman appears immediately. Her prominent nose points toward the left, her mouth forms a thin line, and her chin curves above the dark clothing.

Both faces belong to the same drawing. Neither viewer has misunderstood the picture.

Known as “My Wife and My Mother-in-Law,” this famous optical illusion allows the same lines to form two different portraits. Its fascination lies in the moment when the face you initially missed suddenly becomes visible—and a picture that seemed perfectly clear takes on an entirely different meaning.

The best-known version was drawn by William Ely Hill and published in the American humor magazine Puck on November 6, 1915. The Library of Congress preserves the illustration in its collection. Although earlier versions of the young-woman/old-woman design existed, Hill’s drawing became an enduring example of visual ambiguity.

More than a century later, its appeal remains easy to understand. You need no special equipment to experience it. You simply look—and then discover that looking again can change what you see.

In the accompanying image, the illusion depends on several carefully arranged details. The pale area near the center can belong to a young woman’s cheek and jaw or to the long nose of an older woman. A small curved feature beneath the dark curls can become either an ear or an eye. A dark line lower down can suggest jewelry around a neck or a closed mouth.

These details do not move. Their roles change as you recognize a different face.

The main connections are:

When you see the young woman	When you see the older woman
Her ear	The older woman’s eye
Her chin and jawline	The older woman’s prominent nose
Her necklace or choker	The older woman’s mouth

Once those connections become clear, the drawing may begin to switch between the two portraits. You might recognize the younger woman for several seconds, then suddenly find yourself looking at the older woman again.

If you can see only the young woman, start with her ear. Try imagining that small shape as an eye. From there, follow the outline of her cheek and chin toward the left, treating it as a large nose. Then look below it for the dark line that becomes the older woman’s mouth.

Allow the entire face to form around those features. Sometimes the change happens gradually. Sometimes it arrives all at once.

If you can see only the older woman, reverse the process. Look at her eye and imagine it as the ear of someone facing away. Reinterpret the prominent nose as the outline of a younger woman’s cheek and jaw. The mouth then becomes a narrow band around her neck.

Focus on the idea that the younger woman is turned away from you. Expecting to see a complete, forward-facing face can make her harder to recognize.

The experience illustrates what researchers call an ambiguous or bistable image: a single picture that supports two competing interpretations. In this case, perception can alternate between the younger and older woman even though the visual information remains unchanged.

That distinction helps explain why the illusion feels so surprising. We tend to experience seeing as immediate and straightforward. We look at something and feel that we simply know what it is. This drawing makes the interpretive side of vision unusually noticeable.

A curve becomes meaningful because of the features around it. Once you recognize an eye, the neighboring outline can become a nose. Once you recognize an ear, those same surrounding shapes can organize themselves into a face turned away.

The picture gives you enough information to support either reading. Your first impression is only one way of putting that information together.

There is also something enjoyable about sharing the image with another person. You may find the younger woman so obvious that you struggle to understand how anyone could miss her. Meanwhile, the person beside you may be equally certain that the older woman is the clearest part of the drawing.

Then one of you points to a small detail.

“Look at the ear.”

“Now imagine that it is an eye.”

A brief explanation can make another person’s view accessible. The satisfaction comes from recognizing something that was present all along.

This is where the drawing offers a useful metaphor for everyday life. People can encounter the same words, photograph, or situation and pay attention to different details. One person notices an expression; another notices the circumstances around it. Each may feel that their first impression is obvious.

The illusion invites us to pause before assuming that our immediate interpretation is complete. It encourages a simple question: “What might someone else be noticing?”

That lesson has limits. A deliberately ambiguous drawing does not prove that every opinion is equally accurate or that facts depend entirely on perspective. It does, however, provide a memorable experience of discovering that another interpretation can be supported by details we initially overlooked.

Perhaps that is why this old illustration remains so engaging. Its design is still, but the experience of viewing it can change. A few lines offer a small puzzle, a moment of surprise, and an opportunity to reconsider an apparently settled impression.

Take another look at the image. Follow the outlines slowly. Find the ear, the eye, the jaw, and the nose. See whether you can move between the two faces.

Which woman did you see first—and can you now see them both?
