When I was in high school, I was on the school newspaper. Two of us on the staff were invited to a "press conference" that the Supremes held [[one of the conference rooms in either Strawbridge's or Wanamaker's in Philly), and we were given a copy of this photo to use in a newspaper article if we chose to do so. I think it was either in late 1970 or early 1971. I may still have the photo.
