Original 1st printing 8&1/2 x 13&7/8" concert flyer for a series of (4) Northern California appearances by the Loading Zone appearing with Sopwith Camel and Clover from 8/12-15/1971. Artist unknown, cities listed include Sacramento (8/12), Chico (8/13), Yuba City (8/14) and Placerville (8/15); medium-thin flat textured stock flyer is in good to very good (B to B/B+) condition; a bit of corner/edge wear (a few stray tiny tears and a bit of creasing mostly along the bottom margin), a 1" discoloration/stain in the lower left center margin, a few subtle surface scuffs and handling dings, otherwise a fine-looking example of this patriotically-themed oddball concert flyer from Northern California.
