RCA/NBC Telecast From the 1939 New York Worlds Fair

This photo shows the RCA/NBC remote television crew telecasting an event at the 1939 New York World's Fair.  Note the "snow" and "icicles" on the roof of the building in the background, and the crowd in shirtsleeves!  I don't know the exact location or the event, but as part of RCA's television promotion, events around the fair were routinely covered and could be viewed by visitors to the RCA building.  Cards such as that shown below was given out to fair visitors who had seen themselves on TV, and as a reminder to buy RCA products.
