The Potamkin collection of American art, “one of the best of its kind in private hands,” is being split up after the death of Vivian and Meyer “Pat” Potamkin’s collection. The collection includes an “estimated several hundred paintings, sculptures, and works on paper” and most will be sold at auction by the couple’s heirs. “The Pennsylvania Academy of the Fine Arts, which was widely expected to be the major recipient, gets just a small portion, but it is the choicest and most valuable – eight paintings, one pastel drawing and a sculpture, which are estimated to be worth from $18 million to $22 million.”
