But, it’ll cost ya. Ten missives penned by the glimmer twin in 1969 to Marsha Hunt, the mother of Sir Mick’s first child, Karis, will be up for auction. Hunt told England’s Guardian, “The letters speak for Mick at an incredible juncture of our lives. The summer of 69 was the end of a whole era of revolutionary spirit – we didn’t know it was about to die.” The auction takes place on December 12th in London and the letters are expected to sell for up to 159-thousand dollars.
