Original 1st printing 17&3/8 x 22&3/8" event/concert poster for the 7/1/1970 stop of the Trans Continental Pop Festival, held at Winnipeg Stadium in Winnipeg, Manitoba, Canada.

 Poster (the second stop on the legendary "Festival Express" train tour across Canada) lists appearances by the the Grateful Dead, Janis Joplin, the Band, Buddy Guy, Delaney & Bonnie, Mashmakan, Charlebois, James & the Good Brothers, Eric Andersen, Mountain, Ian & Sylvia and the Great Speckled Bird, Tom Rush and Melanie.

 Design by Ken Walker and John Lown, image (identical image from the Toronto stop) is featured in the art of Rock on page 376 (plate 4.132).

 Thin flat vellum stock poster is in good/decent (B to B/B-) condition; there is a moderate degree of fading/discoloration in the orange borders along the top left and lower left margins, along with a 1/2" tear and a small crescent-shaped nip out of the top margin, a bit of horizontal stress creasing and light moisture warping to the paper, a soft pin-prick stain or two hiding within the image area and a couple of stray handling dings, otherwise fine.

 While the posters from the Toronto and Calgary stops turn up with some regularity, the Winnipeg is MUCH harder to come across, this is only the THIRD example I have seen... a fairly tough find, for sure. Check out the entire "Festival Express" film HERE (Winnipeg show at 24:36):
