One of my favorite signs, informing workers about to descend into the open-top grain bins about basic procedures. This was in ADM-Annex 1 (connected to the cleaning house via skyway), so it will never be seen again, unless the sign lands luckily when the elevator is demolished.
Dominion was acquired by UGG, which designated the elevator ‘M’. Their offices still have safety signage.
Between lines of Number Sixes right after sun rose behind them. This photo shows how extremely lush the grounds are that make getting around in some places impossible.
The Calumet Elevator offices used to be flanked on both sides by rails. Now, only one side has engines running on it.
1950s safety posters about static and proper footware hide in remote offices, where the curious haven’t stolen them… yet.
Kodak Tri-X 400, Leica M7. Serious enough to write across the side of the tank, but not serious enough to have a sign made.
