Original 1st printing 8&1/2 x 11" 1966 Mainstream Records/band-issued promotional flyer for "Blind Man", the debut single by Big Brother and the Holding Company (featuring Janis Joplin).
 
 Art by Stanley Mouse, thin flat stock flyer is in near mint to excellent (A-/B+ to B+) condition; aside from a few stray handling dings/soft creases here and there and a couple of very light bends around the outer margin area/corner tips, it is an EXCEPTIONALLY nice-looking example of this oddball late-'66 Mouse flyer for the VERY FIRST Big Brother record.
