Original 1st printing 8&1/2 x 11" concert flyer for the All-Nite Apothecary appearing at the Matrix in San Francisco, CA from 5/26-28/1967. 

 

 Art by Jack Downing, thin flat stock flyer is in near mint to excellent (A-/B+ to B+) condition; just a few stray light handling dings scattered around the image area and a whisper of edge wear, otherwise it is a SUPERB example of this very unusual-looking Matrix flyer from the summer of '67.
