Original 1st printing 8&1/2 x 11" concert flyer for Big Brother & the Holding Company (featuring Janis Joplin) appearing with Lee Michaels and the Oxford Circle at the Avalon Ballroom in San Francisco, CA from 12/9-10/1966.
 
 Art by Victor Moscoso, image ("Swirley Eyes") is # 38 in the Family Dog/Avalon series.
 
 Thin flat stock flyer is in good (B) condition; all four corner tips have slight surface pulls (tape removal) and tiny little razor slices/nips (removal from a scrapbook), along with a series of tiny edge nicks/staple indentations scattered around the outer margin area, a touch of handling wear, a hint of toning and a couple of tiny pin-prick spots/thin stress bends hiding within the image area, otherwise fine.

 Very presentable example of Moscoso's classic "Swirly Eyes" image from late-'66.
