Original 1st printing 8&1/2 x 11" concert flyer for Big Brother & the Holding Company (featuring Janis Joplin), appearing with the Illusions and Overbrook Express at Maple Hall in San Pablo, CA  from 4/7-8/1967.
 
 Design by Joe Ursini (borrowing heavily from Wes Wilson's design for the FD 5 poster), medium-thick flat stock flyer is in decent (B/B-) condition; there are staple/pin holes in all four corners, along with a small 1/2" tear in the top center margin, a smaller 1/4" tear in the lower right margin, a series of semi-pronounced horizontal creases/bends traversing the image area across "Big Brother", "Illusions" and "Church Lane", a bit of minor handling wear, otherwise fine. 
 
 Very uncommon early-'67 Big Brother concert flyer from a tiny East Bay show, first one of these I have seen.
