Original 1st printing 8&1/2 x 11" concert flyer for the Andrew Staples appearing at the Matrix in San Francisco, CA on 2/26/1967. 
 
 Designer unknown/not credited, thin flat stock flyer is in near mint (A- to A-/B+) condition; just a few soft handling dings here and there (mostly scattered around the outer edges), a soft smudge in the upper right margin and a whisper of mild edge toning, otherwise it is a mostly-clean example of this somewhat basic, but fairly uncommon early-'67 single-show Matrix flyer.
