The family has now seized the artwork.

It concerns a painting from 1918 by the Utrecht painter and designer Bart van der Leck, which is now worth around 350,000 euros.

Silbermann-Frenkel says that she donated the painting in a confused state and that at the time of the donation she was incapacitated.

Her seventeen-year-old granddaughter had a brain tumor.

Voices in Silbermann-Frenkel's head told her to give the painting as a sacrifice so that her granddaughter could survive.

The family says the museum has failed to comply with its duty to investigate.

The current director Taco Dibbits has

informed

in a response

that the museum has acted "in good faith".

If the judge rules otherwise, he will return the painting.
