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 near mint (A- to A-/B+) condition; aside from a couple of minuscule corner-tip dings, a touch of mile edge toning and a well-camouflaged soft handling ding or two hiding within the image area, it is an EXCEPTIONALLY nice-looking example of this popular (and iconic) late-'66 Moscoso image from the Avalon.
