Thursday, August 17, 1967 fell in the middle of one of the most ambitious weeks Bill Graham ever booked. BG-78 covers seven straight nights at the Fillmore Auditorium, August 15 through 21, and the bill reads like a case for the room's whole argument: Chuck Berry, Count Basie and his orchestra, the Charles Lloyd Quartet, and the Young Rascals, with the Steve Miller Blues Band and the cast of Hair also appearing across the run.

Look at what that means. A founding figure of rock and roll, one of the great big bands in the history of American jazz, a modal jazz quartet whose Forest Flower had just made Lloyd an unlikely favourite with rock audiences, and a blue-eyed-soul hit machine from New York — all on one card, in one hall, in one week, in the middle of the Summer of Love. Graham's Fillmore was never only a rock room, and this is the poster that proves it hardest.

The design is Jim Blashfield's first in the Graham series: four slightly out-of-round shapes holding the lead acts' names, in a psychedelic style with avian and human forms, claws of a sort, and mushrooms. He would go on from posters to award-winning animation.
