Original 1st printing 8&1/2 x 11" concert flyer for Big Brother and the Holding Company (featuring Janis Joplin) appearing at the Matrix in San Francisco, CA from 11/1-6/1966. 
 
 Art by (and SIGNED in black flair pen by) Stanley Mouse, image is featured in the Art of Rock on page 164 (plate 2.111).
 
 Thin flat stock flyer is in near mint to excellent (A-/B+ to B+) condition; aside from a couple of light handling bends scattered around the image area/margins, it is a very sharp example.
 
 AWESOME-looking late-'66 BBHC Matrix flyer with a sweet Mouse signature!
