Pair of original 1st printing 14 x 20&3/8" concert poster for Texas blues legend Lightnin' Hopkins appearing at the Matrix in San Francisco, CA from 10/7-16/1966. 

 

 Art by Tom Weller, medium-thick flat vellum stock poster is in FANTASTIC near mint (A-) condition; other than a few loose soft handling dings scattered around the image area, this example is VERY clean/crisp overall.

 

GREAT-looking early (1966) Matrix poster with a really nice design, this poster doesn't seem to turn up often.
