Original 1st printing 17 x 22" concert poster for West Coast Natural Gas appearing with Five Pound Smile, Fifth Pipe Dream and Bentley Escort at San Francisco Sound in Seattle, WA from 2/28-3/2/1968. *also lists an upcoming appearance by Moby Grape

 Art by Wallace Studios (Donna Wallace-Cohen), poster is pictured on page 144 of Scott McDougall's "Split Fountain Hieroglyphics" (plate SFH 116)
 
 Medium flat index stock poster is in good (B) condition; there is a bit of soft edge tattering/wear along the upper left margin and concentrated in the upper left corner, along with a few tiny pressure creases/edge nicks and tiny dings scattered around the outer margin area, a series of very thin horizontal stress/roll bends traversing the image area, a bit of creasing in the lower left/right corners/margins and a few tiny pin-prick spots along the right margin, otherwise OK.

Very presentable example of this somewhat uncommon Pacific Northwest psychedelic concert artifact.
