By Wednesday night at Sotheby's the clouds had moved in and pouring rain was on its way. The barometric changes didn't dampen spirits -- not by a long shot. The sale of the Maggi Weston collection totaled $7,819,700 and was highlighted by a new world record for Edward Weston. His "The Ascent of Attic Angles" from 1921 went to a private buyer in the room for $824,000. The various-owners sale on April 26 brought in $5,203,800. Combined with the sales of the Eugene and Adalbert Cuvelier collection on April 13, the total for Christies was $15,915,500.
