Mad or Sad?
Ambiguous faces have been popular optical illusions for well over a century. We previously featured a vintage ambiguous face that was published in Strand magazine in 1899. In the example below, drawn by Humberto Machado, two different faces can be found. One is a man who looks mad and another is a man who appears to be sad.
Which did you see first? Can you find them both? If you enjoy this drawing, you might also like the previous ambiguous face by Humberto Machado.
