Original 1st printing 19 x 25&1/2" event commemorative poster, "Know Thyself" created for a recent (2018) group exhibit sponsored by Hi-Fructose and held at the Compound Gallery in Oakland, CA, titled "The Art of the Mushroom".

 Art by (and SIGNED in pencil and marked A/P (artist's proof) by) Chuck Sperry, extra-thick cream stock hand-pulled 4-color silkscreen poster is in near mint (A- to A-/B+) condition; aside from a small horizontal bend/soft crease in the right center margin, it is a superb example of this groovy recent Sperry image with a cool design and a timeless message.
