Just watched today for the um-teenth time and a pic caught my eye. It is behind Venkman's desk in the firehouse when Peck makes his first visit. It's the largest pic on the wall, and my best guess is that it's from the '30s. From what I can make out it looks like a group of five-seven people (reverting to memory here so forgive me if I am way off mark), like construction workers of a building. Kind of had a Lewis Hine style/feel to it. I tried to search but to no avail. Anyone have a clue as to what I am babbling about? Just trying to figure out the relevance of the picture to his office and see if it has any ties to the movie. Thanks.
