Original 1st printing 14 x 21" concert poster for Traffic (featuring Steve Winwood) with Spirit, Moby Grape and the Lemon Pipers at the Fillmore Auditorium and Winterland in San Francisco, CA on 3/21-23/1968. Art by Lee Conklin, image is number 112 in the Bill Graham/Fillmore series. Medium-thick flat index stock poster is in fantastic mint/near mint (A/A-) condition; just a tiny bend in the upper right corner, otherwise fine. A gorgeous example of one of Lee's most intricate psychedelic masterworks.
