Original 1st printing 11 x 17" 1970 promotional poster for "Entropy" ("formerly "Gafoo", the Protean University), an alternative adult education center in San Francisco, CA.

 Art by Greg Irons, medium-thin flat index stock poster is in near mint to excellent (A-/B+ to B+) condition; aside from a couple of small bends/minor creases along the upper right margin, a few light handling dings here and there, a bit of light edge/corner creasing and a tiny pin-prick spot on the reverse side that pokes through the paper in the lower left corner, otherwise it is a REALLY sharp example of this bizarre 1970 Greg Irons poster from a presumably short-lived San Francisco entity.
