A series of "passionate and articulate" letters sent by Mick Jagger to his secret lover in the summer of 1969 are to be auctioned off at Sotheby's.
The letters were written by the 25-year-old smusician to American singer Marsha Hunt, who is said to have provided the inspiration for hit track Brown Sugar. The frontman wrote to Marsha whilst he resided in Australia after The Rolling Stones' landmark Hyde Park concert in 1969.
The love notes will join a series of items including The Rolling Stones' song lyrics and playlist by the band, which is expected to fetch up to £100,000.
Gabriel Heaton, Sotheby's books specialist, said: "These beautifully-written and lyrical letters from the heart of the cultural and social revolution of 1969 frame a vivid moment in cultural history.
"Here we see Mick Jagger not as the global superstar he has become, but as a poetic and self-aware 25-year-old with wide-ranging intellectual and artistic interests."
As well as offering insight into the enigmatic singer's pysche, the letters also detail matters of cultural significance during the Sixties, including the first moon landing.
