Original 1st printing 15&3/8 x 22&7/8" concert poster for Quaker City Rock, a one-day show held at the Spectrum in Philadelphia, PA on 10/23/1970.

 Performers listed include: Grand Funk Railroad, Rod Stewart and the (Small) Faces, Eric Burdon & War and Elizabeth.

 Art by Spencer Zahn, medium-thick glossy-coated index stock poster is in excellent (B+) condition; there are pinholes and tiny bends in each of the four corner tips (plus a slight discoloration in the lower left corner tip), along with a light scuff mark and a few handling dings in the left center margin area, a tiny stray edge nick or two scattered around the outer margin area and a tiny bit of tape residue with a bit of toning on the reverse, otherwise fine.

 Uncommon/hard-to-find 1970 1st printing edition of this poster (it was reprinted by Electric Factory promoter Larry Magid in the 1990's), the colors are much brighter on this version.
