I’ve seen this photo on Getty images, so they likely would claim that the organization owns the copyright on all of these images.
“1945 Press Photo Fisherman Uses A Jeep to Reach Distant Trout Fishing Areas. This is an original press photo. Jeep has a future in postwar America The versatile jeep, which has become known as the “Sweetheart of the Army,” has a future in postwar America, both as an agricultural and industrial machine. All kinds of special bodies, air compressors, and pulley attachments for postwar units can be used with the jeep. Here a fisherman uses the jeep to reach the far-back trout streams and lakes. In low, low gear it reaches these distant pastures which are always too far for the fisherman on foot. Photo measures 8 x 6.25 inches. Photo is dated 05-26-1945.”
