MoMa still has so many Nazi-era provenance gaps in 2026

More than 20 years after launching the provenance research project, where is MoMa?

Below are just a couple examples of the kinds of questions that remain:

Otto Dix (German, 1891–1969.) The Nun [Die Nonne]. 1914 Oil on cardboard, 27 5/8 x 20 5/8" (70.2 x 52.4 cm) The Museum of Modern Art, New York. Gift of Gertrude W. Dennis	Accession Number: 253.88 Other works by this artist

After murdering American Mom, Trump's paramilitary thugs murder American nurse in Minneapolis, then lie about it

Every historian of Nazi Germany will recognize the progression of events since 2016, adapted to American soil. Let no one say they did not know what was happening here.  

The Killing of Alex Pretti | Explainer Heather Cox Richardson

After masked DHS thugs murdered Alex Pretti, a VA nurse and an American citizen, Trump officials immediately invented a false story about what happened and spread it aggressively through all their channels.

(see: WIRED: "The Instant Smear Campaign Against Border Patrol Shooting Alex Pretti"

However multiple videos and sworn witness statements prove that Trump, Bovino, Noem, and Patel are lying.
