Chargenplan

A black and white photo. We see from behind a worker in a heavy jacket and hard hat with safety goggles standing in front of a large blackboard. The blackboard is completely covered in a grid giving (in German) technical data of some kind, with hundreds of cells visible in the photo. The worker's head is tipped back and their safety googles snapped to the brim of their helmet, with their head completely invisible; it looks a bit like the goggles are an owl perched on the helmet.
