Original 1st printing 5&1/2 x 8&1/2" concert handbill for Canned Heat appearing with Genetic Dryft at the Community Concourse in San Diego, CA on 6/25/1968.

 Artist unknown/not credited, thin flat stock handbill is in near mint (A- to A-/B+) condition; aside from a tiny 1/2" bend in the lower left corner tip and a couple of nearly-invisible soft handling bends hiding within the image area, this example is just about as sharp as they come.

 Very cool little mid-'68 psychedelic concert artifact from San Diego.
