A major piece of hip-hop memorabilia is about to go up on auction. According to the New York Daily News, famed London auction house Sotheby's is scheduled to offer up a pair of original handwritten lyric sheets penned by 2Pac in 1995 while behind bars. The lyrics correspond with songs featured on the late rapper's All Eyez On Me album, released in 1996. The lyric pages, written on yellow-lined paper, would later come to life in the recording studio in the form of "Ambitionz Az A Ridah" and "Tradin' War Stories."

"We are delighted to have this item in our sale, it's a really unusual item," Gabriel Heaton, the auction house's specialist in books and manuscripts said, according to ITV. "It is the most significant manuscript item that has come to market. He (Tupac) is a fixture of enormous popularity and great cultural significance, so we are confident there'll be a lot of interest."

So how much should we expect these artifacts to go for? Sotheby's is apparently hoping for a winning bid in the range of $47,000 and $78,000.
