London auction house Sotheby’s is preparing to auction off two separate, hand-written lyric sheets from the late Tupac Shakur. The manuscripts were written while the rapper was serving time in jail over sexual assault charges.

One of the manuscripts features lyrics to Tupac’s All Eyez on Me record, “Ambitionz Az A Ridah.”

The New York Daily News reports that the lyric sheet for “Ambitionz Az A Ridah” is expected to sell for as much as $78,000.

“A lot of interest” is expected for the two manuscripts, according to a rep for Sotheby’s.

“[Shakur] is a fixture of enormous popularity and great cultural significance, so we are confident there’ll be a lot of interest,” Gabriel Heaton, a specialist in books and manuscripts at Sotheby’s, said in a statement.

The other manuscript up for auction features nine, hand-written lines from the “Tradin’ War Stories” outro. Both manuscripts feature Tupac’s signature.

The auction is scheduled to begin on September 29 as part of Sotheby’s Rock & Pop auction sale.

In the time since his death, a number of items belonging to Tupac have been auctioned. Most recently, in 2013, a fedora the rapper wore in the “California Love” music video was auctioned.

Tupac’s hand-written lyrics can be found below.
