Original 1st printing 28&1/2 x 22&1/2" uncut printer's proof sheet (three (3) oversized concert flyers and four (4) blank-reverse concert handbills) for the Steve Miller Band appearing with the Youngbloods and Kaleidoscope (featuring David Lindley) at the Carousel Ballroom In San Francisco, CA from5/10-12/1968.
 
 Art by (and SIGNED in black pen by) Alton Kelley, medium flat index stock proof sheet is in very good to excellent (B/B+ to B+) condition; there are a series of light bends/semi-soft handling dings scattered around the outer margin area, along with a tiny pressure crease/tiny nip tear in the bottom center margin, a stray pinch ding or two hiding within the image area and a couple of tiny diagonal corner-tip bends, otherwise it is a VERY nice-looking ARTIST-SIGNED example of this unique 1968 Carousel Ballroom artifact.
