Original 1st printing 11 x 17" concert poster for Cactus appearing with Salem Witchcraft at Cass Tech High School Auditorium in Detroit, MI on 12/20/1974.

 Designer unknown/not credited, medium flat vellum stock poster is in very good (B/B+) condition; there is a 10" hairline-thin stress bend/crease running from the upper right margin (above the "P" of "Presents") down about 1&1/2-2" past the "l" of "School", along with a couple of tiny corner-tip pressure creases, a few light handling smudges scattered around the outer margin area and a mild discoloration in the lower right corner/margin, otherwise fine.

 Really cool little low-run mid-'70's piece from a high school in Detroit, first one of these that I have come across.
