The artist photographed a pair of flight pigeons mating on a target in her 1991 installation of Plain Air at PS 1 Contemporary Art Center, New York. The installation recreates the 1969 original in which two mourning doves were released in the artist’s studio with a suspended 27 inch bicycle wheel. Respecting the larger museum space, the components were doubled in scale and number with a 48 inch bicycle wheel. The title is a pun.
