Original 1st printing 13&3/4 x 19&3/4" cardboard concert poster for the Grass Roots appearing with Majic Theater and South Heart at the Salem (OR) Armory on 6/5/1970.

 Artist unknown/not credited (show promoted by EJD Enterprises), thick cardboard stock letterpress poster is in near mint to excellent (A-/B+ to B+) condition; aside from a couple of tiny edge/corner-tip pressure creases and a couple of hairline-thin stress bends hiding within the image area, it is a mostly-clean example of this low-run oddball 1970 concert poster from the Pacific Northwest.
