Original 1st printing 14&7/8 x 23&1/8" concert poster for Traffic (featuring Steve Winwood, Chris Wood and Jim Capaldi, along with opening act Richard Thompson and Fairport Convention- not listed) appearing on 6/9/1970 and Procol Harum (featuring Robin Trower, along with local openers Brethren and Elizabeth) appearing on 6/19-20/1970, all shows held at the original (2201 Arch St. location) Electric Factory in Philadelphia. Artist unknown, medium-thick glossy-coated index stock poster is in good (B) condition; a hard horizontal center crease, a few soft horizontal roll bends, staple holes and a bit of wear in the four corners, a few stray tiny surface marks (age spots, scuffs and a water spot or two), minor handling/edge wear and a couple of tiny stress bends, otherwise fine. Very amusing-looking Traffic poster from the venerable Philadelphia tire warehouse.
