Pair of original 1st printing 8&1/2 x 11" concert flyers for Eric Burdon & the Animals appearing with the Association, the Bola Sete Trio, the Harbinger Complex, the Baytovens and Sly & the Family Stone at the Oakland (CA) Coliseum on 3/25/1967.

Art by Don Ryder, image (right side) is featured in the Art of Rock on page 220 (plate 2.294), the one on the left is an alternate early pre-show image (fewer bands listed).
 
 Medium-thin flat stock flyers are both in near mint to excellent (A-/B+ to B+) condition; aside from a few ultra-light handling dings here and there (both flyers) and a thin diagonal bend/pressure crease in the upper right corner, a couple of small edge/corner-tip creases and a bit of mild edge toning on the reverse side on the AOR one, they are both in pretty nice shape.
 
 Very cool set of original 1967 Bill Quarry East Bay concert artifacts, I have NEVER seen the "trojan" one before.
