Original 1st printing 19&3/8" x 29&3/4" concert poster for Traffic (with Steve Winwood) appearing on 9/24/1967 (their UK debut) and John Mayall's Bluesbreakers (featuring future Rolling Stone Mick Taylor) appearing with (Peter Green's) Fleetwood Mac(k) and Long John Baldry on 9/17/1967, both shows held at the Saville Theatre in London, England.
Design by Hapshash & the Coloured Coat (Michael English and Nigel Waymouth), image is the second image in Brian Epstein's "Sunday at the Saville" (OAS) series and is featured in the Art of Rock on page 312 (plate 3.188).
Medium to medium-thin flat vellum stock poster has been professionally restored to excellent (B+) condition; a small puncture tear on the "T" of "Traffic (about 1") was repaired, along with a couple of small edge tears that have been sealed, but the amount of real heavy work on this on this one is fairly minimal- it was in pretty nice shape to start with. There is also a nearly-invisible 4" diagonal bend in the upper right corner, a 1&1/2" diagonal bend in the upper left corner and a whisper of surface wear, but overall this example is GORGEOUS.
Unlike the other Saville posters (Hendrix/Floyd, Hendrix/Burdon, Who/Junior Walker), this image wasn't reprinted, making it one of the harder-to-find posters in the series.
