Both books, written by JR Moehringer, share features such as close-up headshot front covers and one-word titles
The Duke of Sussex’s long-awaited memoir titled Spare bears striking similarities to the autobiography of tennis star Andre Agassi, which was written by the same ghost writer.
The cover of Prince Harry’s memoir depicts him looking straight at the camera in an image captured by photographer Ramona Rosales.
The cover of Andre Agassi’s autobiography, Open, published in 2009 also features a front on head shot of the former world number one.
Both books were written by ghostwriter JR Moehringer and also share another noticeably similar feature; their one word titles.
