{"slug":"rosenberg-cross-source-dossier","title":"The Paul Rosenberg cross-source provenance dossier","summary":"A recovered Braque can be followed across official records—but the expected Nazi inventory entry is absent. Two official object images now strengthen identification, while photograph 3492 and final handover proof remain unlocated.","question":"What can cross-source records establish about works connected to Paul Rosenberg that were seized or displaced during the Nazi era, and where do the records preserve uncertainty or disagreement?","answer":"Across Getty, ERR, Rose Valland, Lost Art, the official RBS, primary correspondence in Archives diplomatiques dossier 45.15, and a bounded review of MoMA folder V.A.8, the system can distinguish actors, locate specific displaced works, preserve aliases, and expose two useful negative facts: the Braque is reported as absent from the relevant ERR inventories despite recovery in Brussels, and the inspected V.A.8 surrogate does not supply the referenced photograph 3492. RBS *5034 corroborates the description, 97 x 130 cm dimensions, OBIP number, and Paul Rosenberg as named owner. The 1947 letters connect the generic title Nature Morte to Mandoline, fruits et bouteille, document the Brussels recovery process, and describe restitution to Rosenberg as intended after formalities. The updated official JDP-0056 record now binds two image files to that registered title-and-dimension identity, providing relevant image-based registration evidence without establishing that either file is photograph 3492. The letters and images do not prove the final September handover, complete seizure history, present ownership, legal title, or scholarly novelty. The combined sources support a stronger reproducible research answer, not a legal conclusion.","status":"under-review","channel":"research-leads","revision":"v3","updatedAt":"2026-08-11T16:07:10.335Z","publicationApproved":false,"researcherDecision":{"status":"awaiting-independent-human-review","reviewer":null,"reviewedAt":null},"claims":[{"sourceId":"getty-provenance-index","claim":"Getty has a Paul Rosenberg Group entity connected to at least 25 bounded title-transfer activity leads.","certainty":"database-observation","citationUrl":"https://data.getty.edu/provenance/696a01a7-f2a0-3f42-84e5-7b999cb95016"},{"sourceId":"err-jeu-de-paume","claim":"Braque's Mandoline, fruits et bouteille does not appear in the relevant ERR inventories, but the record says it was found in Belgium and restituted on 12 September 1947.","certainty":"source-assertion","citationUrl":"https://www.errproject.org/jeudepaume/card_view.php?CardId=51346"},{"sourceId":"france-mnr-rose-valland","claim":"Official notice JDP-0056 identifies the same Braque by alternate titles and repeats the restitution, negative-inventory statement, ERR link, Rosenberg archive photograph 3492, and RBS reference.","certainty":"source-assertion","citationUrl":"https://pop.culture.gouv.fr/notice/rose-valland/JDP-0056"},{"sourceId":"lost-art-database","claim":"Official report for Lost Art ID 477894 reconstructs a different Rosenberg work through seizure, ERR exchange, later recovery, and 2015 restitution using extensive archival references.","certainty":"reviewed-report","citationUrl":"https://www.lostart.de/sites/default/files/attachment/document/2024-01/Matisse_ORE_477894_79828.pdf"},{"sourceId":"rbs-tome-2","claim":"The official 1947 RBS Tome II, printed page 227, lists *5034 / OBIP 37.954 as a Georges Braque work described as Une mandoline, des fruits et une bouteille, 97 x 130 cm, owned by Paul Rosenberg.","certainty":"visually-verified-primary-document","citationUrl":"https://www.culture.gouv.fr/rechercher-une-publication-du-ministere-de-la-culture/bases-de-donnees/mnr-historique-de-la-publication/acces-au-repertoire"},{"sourceId":"legacy-explorer","claim":"Legacy Explorer exposes the same target as JDP 51346 and carries the RA1 archival signature plus a main-source link to ERR.","certainty":"cross-linked-database-observation","citationUrl":"https://explorer.rjlegacy.org/object/CardId=51346"},{"sourceId":"proveana","claim":"Proveana's Paul Rosenberg results explicitly distinguish the person, collection, gallery, archive, related Rosenbergs, and the Einsatzstab Reichsleiter Rosenberg organization.","certainty":"first-page-database-observation","citationUrl":"https://www.proveana.de/en/search?term=Paul%20Rosenberg"},{"sourceId":"archives-diplomatiques-209sup-1","claim":"Primary correspondence in Paul Rosenberg dossier 45.15 identifies a 97 x 130 cm Braque first as Nature Morte and later as Mandoline, fruits et bouteille, reports its recovery in Brussels, and describes restitution to Rosenberg as intended after formalities.","certainty":"visually-verified-object-specific-primary-archive-sequence","citationUrl":"https://archivesdiplomatiques.diplomatie.gouv.fr/ark:/14366/m8lz370k5jws"},{"sourceId":"moma-paul-rosenberg-archives","claim":"A complete bounded review of MoMA folder V.A.8 did not reveal photograph 3492 or a secure target-title match.
