«The policeman is visible to all, but not everyone can identify the criminal hidden in this 18th-century French visual puzzle.
France was an important hub for the creation of visual puzzles from the 17th to the 19th century, likely influenced by the rise of offset printing and the growing popularity of magazines.
In a magazine from that era, we discovered a unique visual puzzle.
Unlike conventional puzzles we present, this puzzle doesn’t just depict one person but two.
The obvious character is the policeman, while the hidden one is the criminal he is pursuing.
Finding the hidden criminal may seem elusive at first glance, as the image appears ordinary without any apparent second person.
However, to solve this 18th-century puzzle, one must either rotate the image or, at worst, change perspective.
The suggestion is to flip the image with the building to reveal the hidden character.»
