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 5/19-21/1967. 

 

 Art by Jack Downing, thin flat stock flyer is in BEAUTIFUL mint/near mint to near mint (A/A- to A-) condition; there may be a couple of ultra-soft handling bends hiding within the image area/margins, but for the most part this example is unbeatable.

 

 Very nice little early-'67 Matrix flyer with an odd design.
