Vhils has just finished carving this portrait in Butterworth, Malaysia, for the Urban Xchange Festival. Organised by the same team behind the Hin Bus Depot Art Centre whose efforts have placed the island of Penang on the global urban art map, this year’s edition of the festival saw dozens of local and international artists leaving their mark on the streets of the island’s main city, George Town, and the town of Butterworth, lying on the mainland just across the strait.
