Original 1st printing 11 x 17" concert/event poster for the first Bullfrog Lake Music Festival, held near Estacada (Clackamas County), OR from 7/4-6/1969.

 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 very good to excellent (B/B+ to B+) condition; the upper right corner has a bit of creasing/wear and a pair of staple holes with tiny wedge pulls, along with small diagonal bends in the other corners, a few ultra-light surface stains (only visible when the poster is tilted towards a light source) and razor-thin hairline stress creases hiding within the image area, a soft thin horizontal bend traversing the bottom of the image area and a few light scuffs on the reverse, otherwise fine. 

As an added bonus, this example has been HAND-SIGNED (in blue sharpie) by J.A. members Grace Slick, Paul Kantner and Marty Balin.

 Very neat oddball little PNW festival piece from a somewhat obscure mostly-local festival, allegedly held at-of all places- a trailer park. We also have the smaller 8&1/2 x 11" 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."
