Who?

Who cleans the soot off Mary in Notre Dame Cathedral in Paris?
Who dusts “The Raft of the Medusa”?
Who scrubs the bird droppings off the Henry Moore sculpture?
Who finds the lost masterpiece in the thrift store?
Who shoos the pigeons off the statue of Lincoln?
Who catalogues the works of art in museum basements?
Who comforts the works of art in the empty galleries?
Who laments the art that has already seen its day?
