Memory can disappear with passing generations. With this an inspiration, JR shows the viewer that it is important not to forget what the elderly can pass to the younger generation. Without judging, JR delivers an intimate, unexpected social history in an artistic, poetic and human way. Travelling to Shanghai - a city that has been subject to phenomenal social and economic change, JR creates portraits of elderly subjects, which are then printed in monumental sizes and pasted back onto the cityscape, representing the city's heritage.
