File Museum was the first of Singh's museums. Its 140 images become not only an elegy to paper and its decay in time but also a record of the cupboards, tables and chairs, the lights and fans, that hold this forest of matter and data together in an age of inevitable digitization. But nestling in this timeless labyrinth is an image of a girl on a bed, one of Singh's iconic images, suggesting some secret traffic between the sibling museums.
