Original 1st Printing, 14x20 & 1/2" concert poster for the Canned Heat, Lothar & The Hand People, Allmen Joy and Super Ball at the Avalon Ballroom in San Francisco, CA on 11/3-5/1967. 
 
Art by Robert Fried, image is #90 in the Family Dog, Avalon series. 
 
The poster is in good vintage condition.  The poster has tackholes and staple pulls on all four corners, some light dirt and smudging, and very light creasing.  There is a piece clear of tape on the bottom right corner and near the word super.  It doesn't appear to be holding anything together.  There is a corner bend on the bottom right corner.  This poster was definitely hung up and displayed.
