Original 1st printing 8&1/2 x 11" concert flyer for the Yardbirds (featuring Jeff Beck and Jimmy Page (although Paul Samwell-Smith is pictured) appearing with Harbinger Complex, Peter Wheat & the Breadmen and Just IV at the Carousel Ballroom in San Francisco, CA on 8/25/1966 and at the Rollarena in San Leandro, CA on 8/26/1966. on 7/22/1967.
Art by Don Ryder, image (full-color poster) is featured in the Art of Rock on page 219 (plate 2.293).
Thin flat stock flyer is in good/decent (B/B-) condition; there is a fair amount of toning, along with a series of semi-pronounced moisture stains and tiny pin-prick scuffs scattered around the image area, tack holes and tiny corner-tip nips in the upper left/lower right corners, a semi-flattened horizontal center crease, light handling wear, a soft pull/pin-prick hole in the "u" of "Aug 25" and a few soft bends hiding within the image area, otherwise OK..
Definitely not mint, but still a presentable-enough example of a VERY hard-to-find Yardbirds flyer from the Beck/Page-era.
