Mattel copyrighted the line, “He’s a Doll!” to introduce Barbie’s boyfriend Ken in March 1961 at the American Toy Fair in New York. For more than six decades, Ken has been at Barbie’s side (including a 2004 break-up publicity stunt). Throughout it all, he has consistently reflected the times with his outfits and sparked conversation about popular culture, sexuality, acceptance, play, and gender roles.
