Visitors to the High Line in August — especially those who have visited at night — may have noticed new artwork installed in the windows of Phillips de Pury. Artist Nils Folke Anderson has created After Before and After, a large sculptural installation fabricated from recyclable expanded polystyrene. This installation can be viewed both from inside the Phillips galleries, and from the High Line’s Sundeck. This work will remain on view through September 6. More photos after the jump.
