Original 1st printing 13 x 18&5/8" concert poster for folk icon Joan Baez appearing at the Spectrum in Philadelphia, PA on 1/19/1971.

 Design by Spencer Zahn, medium-thick flat index front/glossy reverse stock poster is in BEAUTIFUL mint/near mint to near mint (A/A- to A-) condition; other than a tiny matte shadow going around the outer margin area and a pair of tiny mounting tape shadows on the reverse, it is an absolutely STUNNING example of this oddball early-'71 regional concert poster from the Spectrum.
