Best Calvin Klein Billboard Ever

The “Calvin Klein” alias was taken by Marty McFly in 1955, after Lorraine Baines noticed the name on his purple underwear. She assumed it to be Marty’s name. Marty did not correct her that it was actually the manufacturer’s name (possibly figuring that she would find it suspicious, as the real Calvin Klein company would not exist until 1968), only told her that most people call him Marty. Lorraine continued referring to him as Calvin, and the rest of the people Marty met in 1955, such as Biff Tannen, did as well. When Lorraine followed Marty to Dr. Emmett Brown’s mansion, he told her that Doc was his uncle.
