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 1/1-6/1966.
Art by Stanley Mouse, image is featured in the Art of Rock on page 164 (plate 2.111).
Thin flat stock flyer is in very good to excellent (B/B+ to B+) condition; there is a thin 1" diagonal bend in the upper left corner, along with a pair of pin holes in the upper left/right corners, a few thin vertical diagonal creases and a light scuff in the upper left margin, a touch of edge toning, light handling wear, a series of soft horizontal creases along the top margin, a few tiny edge dings in the lower left margin and a trace of surface wear, otherwise fine.
Very nice-looking gently-aged example of this classic late-'66 Mouse image from the Matrix.
