Original 1st printing 13 x 20" concert poster for a pair of late-spring 1970 shows held at Mammoth Gardens in Denver, CO; acts listed include: Mountain appearing with Shocking Blue and Blues Image from 5/15-16 and Eric Burdon & War appearing with Fever Tree from 5/22-23;

 Art by John N. Fish, medium-thick flat vellum stock poster is in very good (B/B+) condition; there are tack holes with tiny rust spots in all four corners, along with a bit of creasing and a few tiny edge nips along the upper margin area, a series of light surface smudges/pin-prick spots scattered around the outer margin area, a stray thin stress bend or two hiding within the image area, a subtle degree of toning and a moderate degree of vertical curling to the paper, otherwise OK.

 Very decent-looking example of this low-run mid-1970 schedule-style poster from one of Denver's largest rock venues (current home to Denver's Fillmore).
