White boxes mounted on the walls—they have slices of wood from a zillion-year-old tree, painted white, on their fronts—turn out to be drawers. Pull their handles and you open up a world of color: rainbow graphs of DNA, paintings, drawings, skins, an old photograph of a sedated tiger strapped to a lab table, the muzzle of an actual rifle pointed at your face. Whitewashed is Joseph Gregory Rossano’s love letter to animals that are already gone or going extinct, like tigers and basking sharks and polar bears. Accompanying each piece is an essay written by a scientist and a dollop of fierce affection.
