The database has the artwork record but **no custody history has been ingested** for this work. Here is exactly what the sources returned:

## What the database contains

**One confirmed transaction** (source: `brain_for_art`, Christie's lot essay 17 May 2017):

| Field | Value |
|---|---|
| Auction house | Christie's New York |
| Sale date | 17 May 2017, Lot 27 |
| Sale price (with premium) | $66,800,000 |
| Hammer price | $59,377,778 |
| Pre-sale estimate | $12,000,000 – $18,000,000 |

The result nearly quadrupled the high estimate — one of the largest Basquiat sales recorded at that time.

**Custody history:** zero records ingested. `coverage_gaps: ["no_custody_history"]`

## What this means for provenance

The database explicitly flags: **"Do NOT interpret absence as clean provenance."** The gap flags system (Nazi-era 1933–45, colonial acquisition 1800–1960, Knoedler forgery window 1970–2009) could not run because there are no custody rows to evaluate.

For a 1982 work — post all major historical risk windows — the primary due-diligence concern would be chain of title from Basquiat's studio through to the 2017 seller, which is **not in this database**.

## Where to look for the real provenance record

- **Christie's auction catalogue** for Lot 27, Evening Sale, 17 May 2017 — the lot notes typically list provenance back to the artist's studio
- **Art Loss Register** — check for any theft or restitution claim
- **The Estate of Jean-Michel Basquiat** (represented by the Basquiat Authentication Committee, now dissolved; records held by the estate) for studio-exit documentation
- **AAM Standards on Provenance Research** if you're conducting institutional due diligence

I can only report what is in the database — the 2017 Christie's sale is confirmed; everything before it is data not in DB.
