Art gallery guerrilla invades, Brian Cowen's, National- and Royal Hibernian- Gallery's privacy.

Another ad on for this weeks, "appearing and disappearing" this time with Brian Cowen, the Irish Prime Minister's portraits discovered in the country’s most prestigious art galleries. One in the National Gallery showing the Taoiseach on the toilet, and another in the Royal Hibernian Gallery showing him holding his Y-fronts. The artist reportedly walked calmly into the National Gallery carrying a shoulder bag. He then affixed a prepared caption for the picture to a free space among portraits of Michael Collins, William Butler Yeats and Bono, before hanging his canvas, undisturbed by security.
