In the photo "Lunch atop a Skyscraper" do you think they were up 59 stories or just a few feet from a platform

Answer 1

Although it's possible the photo was "faked", the increasing haziness of buildings in the background suggests depth of field, which in turn suggests they really were up 59 stories.

Answer 2

I am not the best person in the world to work at any distance that I can't easily jump down from.
I don't like heights.

That being said - platform or no platform - in my opinion, the men in the photo are certifiably and absolutely not playing with a full deck of cards.
