On May 29, 1944, proceeding under the Trading with the Enemy Act, the U.S. government seized 401 artworks that Buchholz had shipped to Valentin. According to MoMA’s website, at least one of the seized paintings, August Macke’s Lady in a Park, found its way into MoMA’s collection. Valentin later sold the painting to Henry Pearlman, whose foundation donated it to MoMA in 1956.
