Original 1st printing 15&7/8 x 23" concert poster for Johnny Winter appearing at Mammoth Gardens in Denver, CO on 9/12/1970.

 Art by John Fish, thick textured index stock poster is in very good (B/B+) condition; there are tack/pin holes and tiny pressure creases in all four corner tips, along with a bit of minor edge creasing along the top margin, a series of soft surface stains/pin-prick spots, hairline-thin scratches and a few thin stress bends scattered throughout the image area and a moderate degree of vertical curl to the paper, otherwise OK.

 Great-looking late-1970 concert artifact from Denver's legendary Mammoth Gardens, only the second example I have come across. Check out the show HERE:
