Original 1st printing 16&7/8 x 22&1/8" concert poster for West Coast Natural Gas appearing with Tripsichord Music Box and Five Pound Smile at San Francisco Sound in Seattle, WA from 11/17-18/1967. *also lists upcoming appearances by Moby Grape and It's A Beautiful Day

 Art by Wallace Studios (Donna Wallace-Cohen), poster is pictured on page 108 of Scott McDougall's "Split Fountain Hieroglyphics" (plate SFH 085a)
 
 Medium flat index stock poster is in near mint to excellent (A- to A-/B+) condition; really nothing more than a few stray tiny handling/stress creases hiding within the image area and a loose edge/corner-tip crease or two lurking around the outer margin area, otherwise it is a mostly-clean example of this HIGHLY psychedelic poster from the Pacific Northwest.

 First one of these I have seen in YEARS and the first example I have had available for sale.
