Édouard Manet, Still Life With Brioche, 1880; Carnegie Museum of Art.
There's only a small difference between the original (above) and the updated version of Manet's Nature morte à la brioche, but even so, notice the yellowing in the copy. Excessive editing has dulled the pink rose, altered the coloring of various other elements, and obscured a lot of the detail. A more accurate, first-hand photo is easily available at the museum's website.
