Original 1st printing 16&1/2 x 22&1/2" concert poster for Jefferson Airplane appearing with Lighthouse and John Mayall with Duster Bennett at the Spectrum in Philadelphia, PA on 3/21/1970.

 Artist unknown/not credited, medium-thin flat index stock poster is in good to very good (B to B/B+) condition; six pieces of slightly browned clear tape in all four corners and left/right center margins (about 1-2" long), a touch of toning, very light handling/surface wear and a couple of tiny edge tears along the bottom and right borders, otherwise fine.

 Really cool-looking low-run mid/late-period Airplane concert poster from Philly featuring a sly nod to the home team.
