Original 1st printing 14 x 20&1/8" concert poster for Canned Heat appearing with Allmen Joy at the Family Dog at 1601 West Evans in Denver, CO from 10/20-21/1967.

 Art by (and SIGNED in pencil by) Alton Kelley, image is # D-7 in the Family Dog/Denver series.

 Medium flat index stock poster is in GORGEOUS mint/near mint to near mint (A/A- to A-) condition; an absolutely FANTASTIC-looking ARTIST-SIGNED example of this iconic Kelley image from the Denver Dog. 

 Side note: the infamous Canned Heat "bust" (a set-up which inspired the song "My Crime") apparently took place after the 10/21 show.
