During 4th Prague Biennale(2009) I exchanged exhibited video work called “The best art work in the world”, 2008 by Mexican artist Ruben Gutierrez. For remaking the video, I used the same sound but I made a new drawings. One day I came to Karlin Hall in Prague, entered exhibition space of Prague Biennale, came to DVD players, pressed button OPEN, took the original DVDs out and placed my DVDs prepared at home. After few days the technician found out that there are playing the fake video and informed abut that the organizers of Biennale. The organizers didn’t have the copies of the art works and let my DVDs playing until the end of the Biennale (one month and half).
