Original 1st printing 15 x 22" (appx. -all four margins irregularly trimmed) concert poster for a benefit show held for the Switchboard of Marin, featuring appearances by Dan Hicks & His Hot Licks, Pyewacket, Bronze Hog, Ice, Canterbury Fair, Free & Easy and Blackwater Rising held at California Hall in San Francisco, CA on 12/13/1969.
 
 Artist unknown/not credited, medium-thick flat index stock poster is in used (C+) condition; aside from the irregularly-cut margins, there are a couple of decent-sized surface pulls in the upper left quadrant and along the upper right margin, multiple pin/tack holes in all four corners, light handling wear, a bit of toning, tape pulls on the reverse... definitely a survivor, but it's the only one I have ever seen.

 SCARCE late-'69 California Hall benefit poster.
