Original 1st printing 8&1/2 x 11" concert flyer for the Yellow Brick Road appearing from 3/21-23/1967 and the Congress of Wonders appearing with Morning Glory from 3/24-26/1967, all shows held at the Matrix in San Francisco, CA. 
 
 Art by C. Irvine, thin flat stock flyer is in excellent (B+) condition; aside from a few stray light pinch bends scattered around the outer margin area and a trace amount of edge toning, it is a FANTASTIC example of this oddball early-'67 Matrix flyer from a very eclectic week of local entertainment.
