Original 1st printing 17&1/2 x 22&3/4" concert poster for a late-September 1968 series of shows held at the Matrix in San Francisco, CA.

 Shows listed include: Spooky Tooth with David Blue (9/17-21), Sea Train (9/24-28) with Petrus (9/24-26) and with Cleveland Wrecking Company (9/27-28)

 Art by George Chacona and Marty Rice, image is featured in the Art of Rock on page 166 (plate 2.119).

 Medium flat vellum stock poster is in very good to excellent (B/B+ to B+) condition; there are a series of well-camouflaged soft horizontal roll creases traversing the image area (mostly visible from the reverse side), a few light handling creases and thin stress bends hiding within the image area, a hint of edge toning and a few semi-soft pinch bends scattered around the outer margin area, otherwise it is a fine-looking example of this oddball late-'68 concert poster from the Matrix.
