Led Zeppelin was scheduled to play a sold out concert at the defunct JFK Stadium in Philadelphia Pennsylvania on Saturday August 13, 1977 beginning at noon.  There was no time to book an opening act for the event.  The attendance for the concert was to exceed 90,000.  Four different backstage peel back sticker passes were generated for the concert.  The pass above is a “backstage” pass and had an image of electric factory concerts wolf in a blue zoot suit.
