Andreas Gursky's work has already topped our list of the most expensive photos earlier. This time again his photograph of the Rhine River, dubbed Rhein II, has set a world record. Although estimated at $2,500,000 - $3,500,000, the photograph went under Christie's hammer for $4,338,500. The image is sized at 73 x 143 in. (185.4 x 363.5 cm.). This specific picture is the first from an edition of six that were created in 1999.
