Original 1st printing 8&1/2 x 13&7/8" concert flyer for Nick Gravenites (Electric Flag, Mike Bloomfield & Friends) appearing with the Congress of Wonders at the Matrix in San Francisco, CA from 11/8-13/1966. 

 

 Art by Ruth Garbell, thin flat stock flyer is in very good to excellent (B/B+ to B+) condition; a series of semi-pronounced handling dings scattered around the image area/margins, a 2&1/2" horizontal stress bend extending from the "k" of "Nick", a few thin horizontal/diagonal bends in the upper left margin/corner, a tiny edge tear in the upper right margin and a few stray tiny surface scuffs, otherwise fine.

 

 Cool-looking flyer from the early days of the Matrix.
