Original 1st printing 11 x 16&7/8" concert/event poster for the 7/4-6/1969 Bullfrog Lake Festival, held near Estacada (Clackamas County), OR.

 Designer unknown, poster lists appearances by Jefferson Airplane, Jugerknot, Jimy Holden Trio, Portland Zoo and more (also appeared- (not listed) Sons of Champlin, Ace of Cups and more).

 Medium-thick flat index flat stock poster is in excellent to near mint (B+ to B+/A-) condition; only a few soft handling bends along the top/bottom margins, a nearly-invisible stain in the bottom margin and a stray surface scratch or two, otherwise fine.

 Very neat oddball little PNW festival piece from an obscure mostly-local festival, allegedly held at-of all places- a trailer park. We also have the small flyer for this event listed separately. According to the account over at the Rock Prosopogrophy blog;

"This was a 3-day festival held outside Oregon City (about 20 miles south of Portland) on private land at Bullfrog Lake Trailer Park. Charlie Kelly (Sons of Champlin road manager) recalls that Grace Slick dressed in a Girl Scout uniform, and the Airplane started their show with three quick fireworks blasts and hit the downbeat on the four, electrifying the crowd."
