A series of letters written by the late Harper Lee will be auctioned Thursday.

Alabama's famous author of "To Kill a Mockingbird" and "Go Set a Watchman" wrote 38 letters to friend Felice Itzkoff, who was also from Alabama. The letters will be auctioned at Los Angeles' Nate D. Sanders Auctions, and bidding starts at $10,000.

In one letter, Lee writes to Itzkoff about a conversation her friend and actor Gregory Peck had with President Lyndon B. Johnson, details from the auction showed. Peck told Lee about the conversation, which she relayed to Itzkoff years later in 2009-- on President Barack Obama's inauguration day.

Lee wrote, "On this Inauguration Day I count my blessings...I'm also thinking of another friend, Greg Peck, who was a good friend of LBJ. Greg said to him, 'Do you suppose we will live to see a black President?' LBJ said, 'No, but I wish her well.'"

In a separate letter, Lee recalled a story actress Vivien Leigh had told her about Leigh's ex-husband, Sir Laurence Olivier. In the letter, dated May 2009, Lee wrote, "He was 'on' one night and was considerably annoyed by the 'noise' coming from two people in the audience. 'Somebody making slapping sounds-can't the management put a stop to it?' / 'If you want to put a stop to Helen Keller's enjoyment of your program, have her interpreter be quiet,' he was told. 'It is sometimes rather noisy, when things go as they should.' Of course, Olivier melted, begged Miss Keller's pardon, and gave the rest of his performance in her honor, seemingly unaware of the 'noise.'"

"Vivien was a character and I loved her," Lee wrote.

Lee also wrote about religion, her Southern roots, and the death of screenwriter Horton Foote who worked on the movie adaption of "To Kill a Mockingbird."

The letters are dated between December 2005 to May 2010. Most of the 38 letters were written on Lee's personal stationery, and all but one letter includes the original envelope addressed by Lee.
