Rare handwritten letter by Miles Davis, unsigned, one page, 8.5 x 11, penned on the opposite side of a template letter Davis typed to Irving Townsend of Columbia Records, producer of Davis's classic album Kind of Blue, dated January 23, 1968, in which he inquires whether he may receive "some participation arrangement" for a recording made by girlfriend Betty Mabry, an artist Davis brought to their attention. The handwritten letter, reads, in full: "Dear Irving:--On Jan 23rd I wrote you in regard to Betty Mabry and have heard no word (to date) from you. Although I realize it might take a little time to discuss the 'participation' deal with all concerned, I can't understand why I haven't received the tapes (I requested). If you feel this request is out of line and you can't or won't forward the tape, would appreciate you advising me.-- Sincerely." In fine condition, with a crease to the upper right corner. Accompanied by a full letter of authenticity from REAL. Mabry met Davis in 1967, and after a short time dating the couple were wed in September 1968. Their marriage dissolved a year later, but Mabry's introduction to Davis of trendy artists (including Jimi Hendrix and Sly Stone) and fashions greatly impacted the direction of Davis's musical career. Mabry went on to have a very successful career as a funk and soul singer using her married name, Betty Davis.
