Phaedrus incident
In 2007, an exhibition of Twombly's last paintings, Blooming, a Scattering of Blossoms and Other Things, and other works on paper from gallerist Yvon Lambert's collection was displayed from June to September in Avignon (France), at the Lambert Foundation (Hôtel de Caumont). On July 19, 2007, police arrested artist Rindy Sam after she kissed one panel of Twombly's triptych Phaedrus. The panel, an all-white canvas, was smudged by Sam's red lipstick. She was tried in a court in Avignon for "voluntary degradation of a work of art".

Sam defended her gesture to the court: "J'ai fait juste un bisou. C'est un geste d'amour, quand je l'ai embrassé, je n'ai pas réfléchi, je pensais que l'artiste, il aurait compris... Ce geste était un acte artistique provoqué par le pouvoir de l'art" ("It was just a kiss, a loving gesture. I kissed it without thinking; I thought the artist would understand.... It was an artistic act provoked by the power of Art").

The prosecution, calling it "A sort of cannibalism, or parasitism", while admitting that Sam is "visibly not conscious of what she has done", asked that she be fined 4500€, compelled to an assorted penalty, and to attend citizenship classes. The art work, which is worth an estimated $2 million, was on display at the Museum of Contemporary Art in Avignon.[1][2][3] In November 2007 Sam was convicted and ordered to pay 1,000€ to the painting's owner, 500€ to the Avignon gallery that showed it, and 1€ to the painter.[4] Wikipedia
