Photograph of the ship Collier in the harbor at Sydney, Australia, ca.1920. At center in the distance, a large ship is seen moving through the waters of a harbor. Several windows are visible on the ship's darkly-colored hull near the stern. Three darkly-colored objects are barely discernable along the upper deck of the ship. Near the stern of the ship, a large smokestack can be seen rising above the ship. Above the ship, four large poles can be seen equally spaced. Several wires extend from each pole, and the top of each pole has the form of an inverted triangle. In the far background, several houses and trees can be seen along the Australian shore.
