I’ve posted to Medium a new essay, on the challenges (and possibilities!) of exhibiting things museums don’t actually have. Sometimes, an exhibition developer wants to call attention to the absence of an object from the collection. (Fred Wilson famously did this in “Mining the Museum,” and museums have called attention to NAGPRA-returned objects, or to stolen objects.) Sometimes, you want to recreate, or even create, objects that have been lost, or those that never existed. Take a look.
