Why did Freddie Mercury's parents burn his belongings after he died?
Freddie Mercury's parents and his younger sister, Kashmira, were undoubtedly devastated by his death. They remained out of the public eye as much as possible in the days surrounding the singer's death from AIDS complications. What fans do know, however, is that Mercury's Zoroastrian faith was acknowledged in the time after his funeral. Express noted that, in accordance with the practices of the religion, most of Mercury's belongings were burned.
One thing that was not burned was Mercury's stamp collection.
Joanna Espin, Curator of The Postal Museum, told Express, "When Freddie Mercury passed away, a lot of his belongings were burnt in accordance with his family's religious beliefs. One of the reasons we think this (album) wasn't destroyed upon Freddie's death was because the stamps had originally come from his father."
The stamp album now resides at The Postal Museum for fans and followers of Mercury to visit whenever they want.
