Investigation rationale

Why this may be worth considering

  • maker or artist identity supplied
  • auction estimate is materially below the specialist model
  • all in acquisition cost is at least 55 percent below modelled value
  • all in acquisition cost is at least 75 percent below modelled value
  • Estimate materially below specialist value
  • Weak catalogue discovery
  • very short catalogue title may reduce bidder discovery

Teach the valuation model

Enter the verified hammer price after the auction closes. Only verified outcomes become calibration data.

Learning guardrail

Truth before training

  • Unverified AI output is stored as a hypothesis only.
  • One-source matches are confidence capped.
  • Rejected matches improve source and feature calibration.
  • At least five verified closed sales are required per category.

Automatic signature module

Every artwork image is checked for signatures and marks

The local engine detects and isolates candidate regions, searches the trusted mark library and runs conservative signature forensics. Optional AI interprets unreadable regions and creates research queries without changing the forensic verdict.

Signature regions0
AI enrichmentLocal only
PipelineNot run

No automatic mark result yet

The module runs during normal analysis when a local image is available.

Marks laboratory

Isolate and identify signatures, hallmarks and maker marks

110 independent methods generate cleanup variants, stroke and symbol descriptors, library matches, trust controls and conflict warnings.

Open mark library

Match an unknown mark

Upload the tightest available crop. Include a little surrounding surface so the system can separate paint, engraving, glare and background.

Add a known reference

Signature forensics

Check consistency with known genuine variation

This does not declare a signature genuine. It measures fit against a multi-source reference set, confusing signers and natural variation.

No forensic check yet

Run mark matching first, then compare the questioned signature against a sufficiently broad trusted reference set.
