Now I remember. I mentioned the longer film in passing here, but Joe has clipped out the best parts relating to Pittsburgh. But man... I know my friends at the conference would at least be a little more subtle in their marketing these days, but check out this film from the 1950's:
There are a few things about this. While the history of cleaning up the air gets more attention in retrospect, I am pretty sure that if you seriously tried to assess what took up the conference's time in it's early years I bet it was more the issue of parking, in particular Downtown parking. , This thesis from1950 goes right along with that film clip. It's just an undergraduate student thesis, but has an interesting provenance. See: The Allegheny Conference for Community Development for Pittsburgh, Pennsylvania (warning, large file) by John David Weidlein. May 1950.
and non sequitur, but speaking of cars.. I wouldn't trust my thoughts on retail trends in just about any context, but I really suspect this car may be a big seller here. It's just enough bigger than a smartcar to be practical, and I am guessing it will have a price point well below a mini. Just a thought.
