Print, Photographic

One black and white photograph of one of the winch engines that was used to pull the Lakehead Pipeline across of the Straits of Mackinac. The photo shows a back corner view of the large diesel-powered winch which is mounted on a concrete slab in a construction staging area. A workman is standing beside the engine and has his left hand resting on a conduit. A sign on the side of the winch reads "Collins & Gallucci, Houston - New York, Riverman Winch, Max Single Line Pull 425,000 Lbs., Designed & Built by Collins Construction Co.-Victoria Machine [?]." Evergreen trees are visible in the background.
