With Diamondhead looming behind them and what appears to be a warship in the distance, this foursome is golfing at the famed Oahu Country Club in Hawaii. Founded in 1906, Oahu was Hawaii’s fourth golf course and is located in a valley between Honolulu and the Pacific Ocean. The first nine holes opened in April of 1907 — a few weeks before Autochrome plates were first marketed — and the second nine holes opened in 1913.

While it is difficult to estimate the age of this photograph, Autochromes stayed in production well into the 1930s. An image of this size would have required a bulky plate camera on a tripod, a sight increasingly rare among vacationers in the 1920s. Because of the much greater convenience and compactness offered by rollfilm cameras, the Lumiere company introduced a flexible film version of the Autochrome process called Filmcolor in 1932. Improvements were made to that film to enable shorter exposures, but the appearance of Kodachrome (1935) and Agfacolor (1936) films quickly made the beautiful Autochrome plates obsolete.
