The most expensive photograph ever sold is "Rhein II" by German photographer Andreas Gursky. It sold for $4.3 million at a Christie's auction in 2011. "Rhein II" is a large-format photograph that depicts the Rhine River in Germany. The photograph is notable for its minimalism and muted color palette. Gursky created an edition of six prints of "Rhein II," and the print that sold for $4.3 million is the largest of the edition, measuring over 13 feet wide. However, it's important to note that the most expensive photograph ever sold can change as the art market fluctuates and new sales occur.
