Love letters that were written by Rolling Stones singer Mick Jagger to American singer Marsha Hunt, the love letters were sold at Sotheby’s on Wednesday for $301,000.

“The passage of time has given these letters a place in our cultural history,” Hunt said after the London sale.

“Their inner thoughts should not be the property of only their families, but the public at large, to reveal who these influential artists were — not as commercial images, but their private selves,” Hunt told Britain’s Guardian newspaper.
