Freddie Mercury, the legendary Queen frontman known for his flamboyant music and larger-than-life public persona, is still making headlines decades after his passing. This week, an array of treasures from his eclectic personal collection at Garden Lodge, his former residence, are set to go under the hammer at Sotheby's. The auction, titled "Freddie Mercury: A World of His Own," kicks off on Wednesday, just one day after what would have been the iconic singer's 77th birthday.
