Mona Lisa.

Commerce To India, where an alteration to Mona Lisa apparently has the art world apoplectic:

"The original painting of Italian painter Leonardo da Vinci has remained "the best known, the most visited, the most written about, the most sung about, the most parodied work of art in the world". At the ongoing Jaipur Art Festival which is underway at the Diggi palace, digitally altered image of Mona Lisa has left the art fraternity fuming. In order to publicize its dairy products, RCDF which is also one of the sponsors of the 5-day event has placed photo shopped posters of Mona Lisa at the venue. To attract artists and art lovers, it has also been re-christened as 'Sarasolisa' from Mona Lisa. Without any prior permission, the dairy officials did this to mingle art with the brand."

Best not direct the quoted artist who's clearly very distressed to this Google Image search with its many hundreds of other examples. Excellent headline nonetheless.
