It's well worth taking the time to recognize the salt of the earth that was within the men in this photograph, and the many others who were not photographed.
What a crucible this time period and this profession was! It was sink or swim or spend all day walking on a four-inch wide steel girder. Their courage and perseverance represented more than just American culture, but the modern era itself.
This documentary film doesn't allow the viewer to miss the "every man" aspect of not just the men who did the construction work, but the photographers who put themselves in harms way in order to give record to those feats of construction.
How many of those men on the girder were hired off the back of a truck that same week? None of them including the photographer who took the photo were ever kept in any company record.
