The new brainteaser is hiding a club card featuring the four-leaf clover instead - can you spot it in under one minute
The Cloisters or Flemish Hunting Deck, constitutes the only known complete 52-card deck of cards from the 15th century.
The cards originated in the southern Netherlands and feature four suits, each consisting of a king, queen, jack and ten numeral or pip cards.
The suits are not the familiar spades, clubs, diamonds and hearts but are based on equipment associated with the hunt — horns, dog collars, hound tethers and game nooses. The value is indicated by appropriate repetitions of the symbol.
The figures are thought to be based on Burgundian court costume, dating the cards to before 1480.
In 1983, the Metropolitan Museum of Art in New York bought the set for $143,000 from a wily Dutch antiques dealer who'd purchased it for $2,800 a few years earlier at auction, having noticed that they were much older than their listed 16th-century date.

The precise game being played with the cards is unknown. It may have been Gleek, a three-player trick-taking game, with elaborate rules, popular throughout the 16th century.
The game used a regular deck with the 2s and 3s removed, so there were 44 cards.
