Original 1st printing 8&1/2 x 11" concert flyer for the New Riders of the Purple Sage appearing with Charlie Musselwhite and Mickey Hart & the Heartbeats and Bobby Ace and e (Weir) and His Cards From the Bottom of the Deck (AKA the Grateful Dead) at the Family Dog on the Great Highway in San Francisco, CA from 4/17-19/1970.
 
 Art by Randy Tuten, image is FD-700417 in the Family Dog/Great Highway series. (Eric King designation)
 
 Thin flat stock flyer is in excellent (B+) condition; just a few stray handling dings/ultra-soft bends scattered throughout the image area and a VERY subtle moisture wave along the top margin, otherwise it is a SUPERB-looking example of this semi-uncommon early-'70 Grateful Dead/NRPS concert artifact from the Great Highway.
