In 2023, the heirs of Karl and Rosie Adler sued the Guggenheim to claim the restitution of a Picasso painting, ''Woman Ironing'' (''[[Woman Ironing|La repasseuse]])'' (1904), which the Adlers sold to [[Justin Thannhauser]] in 1938, allegedly for a fraction of its value, to escape [[the Holocaust]]. They alleged that Thannhauser knowingly purchased the painting, and art from other Jews on the run, profiting unfairly from their distress.<ref>{{cite web |last=Owoseje |first=Toyin |title=A Jewish family fleeing the Nazis sold a Picasso in 1938.
