An archive of letters by legendary rapper Tupac Shakur will star in Bonhams' entertainment memorabilia auction in Los Angeles on March 1.

Each will be sold as a separate lot, with estimates ranging from $1,500-2,000 to $3,000-5,000.

Tupac Shakur was one of the biggest stars of the 1990s

They contain an insight into Shakur's thoughts and feelings on some of the darkest aspects in his biography, including his imprisonment for sexual assault and his shooting outside the Quad Recording Studio in 1994.

All were written during his incarceration at the Clinton Correctional Facility in 1995.

There has been a renewed focus on Tupac's life and career of later, with a new exhibition of his writing currently on display at the Grammy Museum in LA.

Filming on a major new biopic will began later this year.

Catherine Williamson, Bonhams' director of entertainment memorabilia, commented: "The popularity of the music and writings of Tupac Shakur continues to grow, and memorabilia of any kind relating to the rapper is exceedingly rare at auction.

"We anticipate great public interest in this material."

The sale will include a number of other pieces of musical history, include a setlist by Kurt Cobain of Nirvana that carries an estimate of $6,000-8,000.
