What is calico jacks flag?

Calico Jack's flag is a well-known pirate flag, also known as the Jolly Roger, used by the pirate named John Rackham, who operated in the early 18th century. The flag was black, with a skull depicted in the center, wearing a red bandana and two crossed swords beneath it. The skull on the flag had a pair of crossed bones beneath it, instead of the traditional hourglass iconography, signifying a death warning to their enemies. Calico Jack's flag was a variation of the traditional Jolly Roger, and its unique design was often different from other pirate flags. It became one of the most recognizable symbols of piracy during the Golden Age of Piracy. Calico Jack was known for his daring raids on merchant ships and Spanish galleons in the Caribbean, and his flag was a symbol of his feared reputation and ruthless nature.
