Bristol welcomed around 50,000 visitors from across the globe as it hosted Europe's largest graffiti festival: This year, Upfest celebrated its 15th anniversary featuring more than 300 artists giving visitors the chance to witness these spectacular creations come to life first hand. Alain, as first and only Luxembourgish artist to this date, was given the opportunity to participate and created this Lucky Mope piece. The murals will be complete for viewing while the artists paint live alongside music stages and food and drink experiences on the festival weekend at the Greville Smyth Park.
