Photo Credit: Great Bridge Links.Unlike his counterparts, the King of Heartsdoesn't have a mustache. One theory is that he used to have one, but lost itduring a printing mishap, and the mistake has remained for generations.While the game of cards is an ancient pass time, cards as we know it today are aresult of around 500 years of slow adaptation and evolution. The Frenchinvention of the set gained traction in the 17th century and accounts for theversion we generally use today. At that time, playing cards were stamped using wooden stamps. Each card wascarved by hand, copying the previous design. Over time these wooden blocks wouldbe worn down, making the drawing less and less vivid. When copying the cards,manufacturers began to skip the mustache due to its fading visibility. It islikely for this reason that King of Hearts looks a bit like the sword isemerging from his head – originally he had an axe, but as the cards began tochange in manufacturing the point of the axe head disappeared and the handleturned into a dagger.
