According to a note I received about this Powerpoint slideshow (that's right...Powerpoint again), someone had a close friend in Panama who forwarded it. It contains photographs taken in the 1920's of construction workers atop skyscrapers eating lunch, relaxing, etc. straddling steel girders 70-80 stories up over the Manhattan skyline. Explanations and captions are all in Spanish - just ignore that - it is the pictures that are so spectacular. Enjoy. http://www.zapateira.com/uploads/Al...ps?PHPSESSID=4ed7708e12a8e6919fa4693e0114eade
Damn Powerpoint!! Arrggghh. I can't see them, but I know the kinds of photos you are talking about. And I love them.
