Original 1st printing 11 x 16&3/8" concert poster for Canned Heat appearing with Genetic Dryft at the Community Concourse in San Diego, CA on 6/25/1968.

 Artist unknown/not credited, medium-thick flat index stock poster is in decent/used (B/B- to B-) condition; a series of pronounced hard horizontal/diagonal bends traversing the image area (from the reverse, it appears as though the poster had been folded into a paper airplane at one time), plus a moderate to heavy amount of edge/corner creasing, numerous scattered stress/handling bends, tiny pin-prick surface spots, scuffs and a fairly large tape pull on the reverse, otherwise OK...

 An uncommon oddball Southern California concert poster that still presents itself in a charming way, conditional issues aside. Very cool little San Diego item.
