People (September 15, 1997)
Diana, Princess of Wales died in a car crash in Paris on August 31, 1997. A beloved public figure, the outpouring of grief that ensued was immense, and it’s not surprising that the September 15, 1997 issue of People magazine, which featured her on the cover, sold 5,206,999 copies.
That issue was not the first time she had appeared on the cover. According to the American Society of Magazine Editors, who ranked this one at number 36 on its October 2005 list, she had appeared on the cover of People magazine 52 times.
