According to the auction house — Nate D. Sanders Auctions — MJ wore the mask (above) while rehearsing for his “This Is It” concert tour on June 24th, 2009 … the singer’s last ever rehearsal.
The auction house claims the mask — made of silk fabric, personally designed by the King of Pop — contains visible traces of MJ’s stage make-up along with a strand of his black hair.
One of MJ’s former bodyguards was in possession of the mask, and swears by its authenticity. MJ famously wore surgical masks outdoors as a form of disguise.
