Original 1st printing 8&1/2 x 11" concert flyer for Sandy Bull appearing with Dan Hicks at the Matrix in San Francisco, CA from 11/30-12/2/1967. 

 Art by S.J. McLellan, thin flat stock flyer is in near mint to excellent (A-/B+ to B+) condition; really nothing more than a couple of tiny soft corner-tip/edge bends and a slight scuff mark/pin-prick spot on the reverse, otherwise it is a mostly-clean example of this BIZARRE-looking late-'67 Matrix flyer.
