Freddie Mercury left many of his possessions to his longtime friend and confidant, Mary Austin, in his will. Now, those items will soon be on display and later be auctioned.

About 1,500 items will be heading to four Sotheby’s locations this summer. The auction house announced the collection is being dubbed “Freddie Mercury: A World of His Own.” The collection is heading to the following Sotheby’s locations on the following dates:

-New York: June 1-8
-Los Angeles: June 14-18
-Hong Kong: June 26-30
-London: August 4-September 5

Sotheby’s notes, “This collection has remained at Freddie’s beloved Garden Lodge for over three decades and displays a quality and diversity of works that are a testament not only to his passion, but his brilliant mind.”

The auction of Mercury’s items will take place in London over the course of three days on September 6-8. Items heading to auction range from stage costumes to hand-written lyrics to pieces of art Mercury collected.

As previously reported, Mercury designated in his will that Austin would receive 50% of his share of future Queen earnings while designating 25% to his parents and 25% to his sister, Kashmira Bulsara. Since the passing of Mercury’s parents, their 25% share has now gone to Austin.

5 Best Performances from the Freddie Mercury Tribute Concert

Freddie Mercury left this Earth on November 24, 1991. While he left a void in the rock landscape that is still felt today, his inspiration has transcended his era, and he continues to influence new generations of music fans.

He also transcended musical genres: about five months after his death, Queen, along with an all-star lineup, put on The Freddie Mercury Tribute Concert for AIDS Awareness. The concert was held at Wembley Stadium before a massive crowd of 72,000 on April 20, 1992. Proceeds from the show went towards launching The Mercury Phoenix Trust, an organization founded by Brian May, Roger Taylor and Queen manager Jim Beach that has help fund numerous projects in the fight against HIV/AIDS.
