Late last week, Marc Jacobs and French graffiti artist Kidult were involved in a little tête-à-tête, if you will: It began when Kidult allegedly vandalized Jacobs's SoHo storefront with his signature gigantic letters, spelling out the word 'ART.' In lieu of pressing charges, Jacobs retaliated by releasing a super limited edition $689 cotton tee featuring a photo of his shop's blemished facade, which read 'Art by Art Jacobs.' But the graffitist got none of that $689 per shirt (if MJ even sold any), and he was maaad. Kidult's menacing Twitter response to this 'collaboration?' "LET’S PLAY, but we don’t play the same rules!” Scary stuff. Well, it looks now like someone else doesn't play by those same rules either.
