There are precious few weeks left before the end of the year gets swallowed up by holidays and family trips. The galleries seem to sense this, and are pulling out their big guns to lure art lovers from the press of holiday festivities. In New York, the Marian Goodman Gallery is putting up a Francesca Woodman retrospective and Edwynn Houk Gallery is showing Sally Mann's Immediate Family work. In Toronto, Stephen Bulger Gallery has an exhibit of Ruth Orkin's classic American Girl in Italy series. Also just in time for the holidays, there are a few book signings this week: Richard Miscrach at the Pace/MacGill Gallery, Pieter Hugo at Yossi Milo, and a spate of photographers and artists at the Rizzoli Bookstore, all in New York.
