 Photocopy of original sales list per Christie’s, received May 2005; Christie’s have no record of Rosenberg in connection with this sale, beyond the notation in the sales catalog.
 Presumably this Rosenberg is connected with the firm that handled the painting again later, as is so often the case. There was at the time more than one Rosenberg involved in the art market.
 Krempel, 2000, lists “L. R. Ehrich,” which is here emended to “H. L. Ehrich.” He also notes a San Francisco exhibition (1927) while the painting was under control of Ehrich.

An attorney representing members of the Oppenheimer family presented a claim regarding this painting, and a number of others in the Putnam Foundation collection, in 2004. Although the family lost a number of works to Nazi looting, none of the Oppenheimer paintings, which were sold in early 1935 in a Nazi-sanctioned auction, correspond to pieces owned by the Timken. The inquiry to Noortman Gallery, Maastricht, has resulted in some additional information: Mr. Eddy Schavemaker of that firm provides in an email of August 1, 2005, recent contact information for Mr. Brod, who is apparently still living. The dealer Rosenberg and Stiebel, New York, (known to house the painting 1974–79), still does business as Stiebel, Ltd., under the management of Gerald Stiebel. To date, research has uncovered nothing to connect the painting with that of the famous Paris dealer Rosenberg, nor any other known looted collection.
