QuoteNot quite a list of FORD antendees, but...
I found a list of the FORD Board of directors in July 1965 with a photo
Good catch. It helps present a potential list of SA attendee suspects.
Plus an interesting source, the Walter P. Ruther Library. It illustrates looking around other tangential automotive collections because you never know what photo/scan/pr release/ newsletter that someone has archived.
I still remain bemused that it seems, thus far, to appear that someone from Ford PR didn't cover the event showing Ford executives more closely since this was the Total Performance era that Ford was promoting full time.
