The Saturday photo, part XII: Juan Antonio Samaranch, recently deceased former president of the International Olympic Committee, performs a fascist salute in 1974.
For more details on the photo, see this article from The Times. See also Andrew Jennings, “Why Juan Antonio’s right arm is more muscular than his left (It’s had more exercise!) The Love that Dare Not Speak its Name”.
Hat-tip to my friend Jaume Subirana.
