Original 1st printing 18&3/4 x 25" concert poster for Traffic (featuring Steve Winwood) appearing with Quicksilver Messenger Service and the Crumbs at the Shrine Exposition Hall in Los Angeles, CA from 3/29-30/1968.
 
 Art by John Van Hamersveld, image is featured in the Art of Rock book on page 276 (plate 3.67) and is part of the Pinnacle Presents series.
 
 Medium-thick flat index stock poster is in excellent (B+) condition; there are a series of tiny rub marks/scuffs along the bottom margin, along with a few tiny pressure creases scattered around the outer margin area and a couple of stray handling dings hiding within the image area, otherwise it is a mostly-clean example of this always-popular 1968 Pinnacle poster with a great Van Hamersveld design and a killer lineup.
