Original 1st printing 8&1/2 x 11" concert flyer for Quicksilver Messenger Service appearing with Osceola and the Robert Savage Group at the Family Dog on the Great Highway in San Francisco, CA from 4/24-25/1970.
Art by Randy Tuten, image is an un-numbered image from the Family Dog/Great Highway series (FD-700424-OHB-A in the Eric King guide).
Thin flat stock flyer is in very good to excellent (B/B+ to B+) condition; there are a couple of soft brown age spots in the bottom center margin, along with a pair of semi-soft diagonal bends (about 2-3" long) in the lower right margin a few light hairline bends scattered around the outer margin area and a stray pinch ding or two lurking within the image area, but overall it is in really nice shape.
Very cool-looking late-period Great Highway flyer.
