Lily Bass (Kelly Rutherford) hosts an auction to benefit the APF featuring art from her own personal collection, including one of her favorite pieces — “Spectrum,” by Richard Phillips — which has held a prominent place above the stairs in her apartment for many years. When CHUCK (Ed Westwick), Ivy (Kaylee DeFer) and Lily each decide they want the Phillips for their own reasons, a bidding war ensues.
In addition to Phillips' “Spectrum,” pieces by Patrick McMullan, Jessica Craig Martin and Marilyn Minter — all of whom have had their work previously featured on the GOSSIP GIRL set — are featured in the episode, along with pieces by Kehinde Wiley, Miltos Manetas, Josephine Meckseper, Dustin Yellin, Spencer Sweeney, Chris Dorland, Todd DiCiurcio, Pierre Elliot and Fab 5 Freddy, appearing for the first time in GOSSIP GIRL.
Richard Phillips’s piece "Lindsay III (2012)," featuring Lindsay Lohan, also appears in the episode.
In addition to having their work featured on screen, Phillips, Sweeney, McMullan, Fab 5 Freddy, DiCiurcio and Doreen Remen, co-founder of the APF, make cameo appearances in the episode.
