Original 1st printing 8&1/2 x 11" concert flyer for the Sparrow (featuring several members of Steppenwolf) appearing at the Matrix in San Francisco, CA from 5/9-11/1967. 

 

 Art by Jack Downing, thin flat stock flyer is in ultra-sharp near mint (A-) condition; just a couple of nearly-invisible handling bends hiding within the image area and a couple of tiny corner-tip bumps, otherwise fine.

 

 Neat-looking little oddball Matrix flyer from mid-1967.
