Photograph of an array of pipes at a Department of Public Works plant, [s.d.]. At left, a man in a long-sleeved shirt and a porkpie hat stands near a shoot of six pipes and a propeller of some sort, both of which extend through the ceiling above. The surrounding room appears to be a tub or chamber of some sort.一张拍摄于公共工程署（Department of Public Works）厂房内的管道阵列照片，拍摄日期不详（[s.d.]）。画面左侧，一名身着长袖衬衫、头戴圆顶窄边礼帽（porkpie hat）的男子正站在六根管道的引出结构与某种螺旋桨装置旁，二者均从上方的天花板穿出。该房间整体看起来为某种储槽或腔室结构。
