Above is the letter Jim Morrison sent artist Thomas E. Breitenbach in response to Breitenbach’s earlier offer to paint a record cover for the Doors. Morrison’s concept, in part: “Try doing a triptych. The left panel depicting a radiant moon-lit beach and an endless stream of young naked couples running silently along the water’s edge. On the beach, a tiny infant grins at the universe and around its crib stand several ancient, old people.” The other two suggested panels are, of course, equally bonkers. Morrison would die less than a year later, but the triptych survives at Breitenbach’s blog, as does the rest of the transcription of the letter, courtesy of the always reliable Letters of Note.
