Original 1st printing 8&1/2 x 11" concert flyer for Quicksilver Messenger Service appearing at the Matrix in San Francisco, CA from 11/15-17/1966. 

 

 Art by R. Lyons ("R.A.L. Cards"), thin flat stock flyer is in excellent (B+) condition; there is a tiny bit of pen scratch ("1966") just to the right of "17th", a few tiny creases and a thin horizontal roll bend across the top margin, a tiny 1/8" tear in the right center edge, a few light bends along the right margin and a few ultra-soft handling dings scattered around the image area, otherwise fine.

 

 VERY hard-to-find (and cool-looking) late-'66 Matrix flyer.
