Memorabilia enthusiasts should keep this sale on their minds.
Guernsey's will auction off more than 2,000 items, including a pair of Willie Nelson's famous braids, from musician Waylon Jennings' collection on Sunday.
"Many items from fellow artists are brilliantly preserved in Jennings' collection, which stands as a timetable and testament to his calling in life. Unpublished photographs, favorite stage outfits, instruments, music awards and stage equipment are among the countless treasures to be sold," the auction house said on its website.
The braids are expected to raise $50,000 to $60,000.

Nelson and Jennings collaborated on a duet album called "Waylon and Willie" that was released in 1978. Nelson cut off his braids in 1983 to support Jennings during his recovery from cocaine addiction.
Other items on the auction block include a handwritten letter from John Lennon, Muhammad Ali's robe and a motorcycle that once belonged to Buddy Holly whom Jennings once performed with.
Jennings was a member of The Highwaymen, a country music "supergroup" that included Nelson, Johnny Cash and Kris Kristofferson. Jennings died in 2002.
The auction will be held at the Musical Instrument Museum in Phoenix.
