Identical Twins, Roselle, N.J. Young twin sisters Cathleen [left] and Colleen Wade stand side by side in dark dresses. The twin on the right slightly smiles and twin on the left slightly frowns. This photograph is echoed in Stanley Kubrick's film The Shining, which features twins in an identical pose as ghosts. A print was sold at auction for $478,400 in 2004.
