A photo folder from the legendary Washington DC club Bohemian Caverns; jazz clubs of the era had roving photographers who would shoot patrons at their table, and you could take the photo home as a souvenir at the end of the night. Instead of a photo inside, this has the autographs of John and Alice Coltrane.  Alice was married to John from 1965 to his death in 1967, so this was signed sometime between those years, when Coltrane’s band played the club.  Alice, a pianist and composer is highly revered and collected too, and her autograph is very rare.
