There is both a mystery and a commercial industry surrounding this poster for the June 1967 Hunter’s Point Festival honoring Muhammad Ali. The poster announces the free two-day concert, featuring the Steve Miller Blues Band, the Sonny Lewis Quintet, Radha Krishna Temple, and others, including many special guests. The problem is that there is little to no record of the festival actually taking place. One of the bloggers over at Rock Prosopography has followed the trail closely and you can check out that post HERE. The Virtual Museum of the City of San Francisco, for example, lists the event but reviews of any kind are harder to come by.

In the meantime, this has not stopped entrepreneurial resellers from giving the poster, which is apparently a limited edition work of psychedelic art, a second life. One seller cites Christie’s as declaring there are only three posters available in the world.
