Our contributor Dereck Stafford Mangus’s day job is museum guard at the Baltimore Museum of Art, but Dereck also works as a member of the museum’s conservation crew dusting the sculptures in the sculpture garden. Recently, the dusting tasks came up against the demolition of a building next door to the museum, on the campus of Johns Hopkins University, triggering Dereck’s thoughts about demolitions in general and the labor of artists and conservators. Enjoy this behind the scenes look at a different kind of museum work. All photomontages by Dereck Stafford Mangus.
