calder sale art detective 2639120

An Alexander Calder mobile, *Big Horizontal Red* (1956), estimated at $5–7 million, is set for auction at Christie’s on May 12. The work’s provenance traces through Perls Galleries, the Texas Institute for Rehabilitation and Research, and a private New York collection, but a source reveals that its 1997 purchaser, Patricia Halterman, was the granddaughter of Magda Goebbels, wife of Nazi propaganda minister Joseph Goebbels. Christie’s declined to comment on the consignors but stated it conducted careful evaluation and diligence.
