About John Grillo
Born

Died

Nationality
American
John Grillo (1917–2014) is identified in the collected Wikidata record as an American artist. The source pack also links his identity to Getty ULAN, VIAF, the Library of Congress, MoMA, RKD, and the National Gallery of Art, although those pages were unavailable to the collector or returned no excerpt. These identifiers are useful for entity matching because the collected Wikipedia title result instead describes John Martin Grillo, an English actor, and is not evidence about the artist. The available pack does not reliably establish Grillo’s training, movements, media, subjects, exhibitions, or named series, so this profile does not expand those areas from prior knowledge. Appraisily associates 335 auction-directory records with the public artist page; collectors should treat them as a starting set that still requires lot-level identity and object review.
Common works and media
The collected sources do not establish which media, subjects, editions, paintings, prints, drawings, sculptures, or other work types commonly appear under John Grillo’s name. Each potential work should therefore be classified from its own cataloguing, images, measurements, inscriptions, provenance, and attribution evidence before comparison.
Market and appraisal context
An appraisal should begin by confirming that a work belongs with the American artist’s authority and museum records, particularly because a same-name actor appears in search results. The supplied pack associates 335 records with Appraisily’s John Grillo page but does not provide their media, dimensions, dates, condition, provenance, attribution language, editions, or individual results. Those details must be reviewed before selecting comparables. When available, relevant auction-house context, sale dates, realized prices, and closely comparable lots can help frame the market. This profile does not infer a price trend, scarcity claim, or value forecast from the record count alone.
Auction categories and appraisal factors
Value drivers
- Comparison with relevant public auction records, including realized prices and sale dates when those details are available
Appraisal caveats
- The supplied source pack reports 335 associated records but does not expose lot-level descriptions or results for verification.
- No collected source establishes common media, subjects, editions, attribution terminology, condition patterns, provenance, or date-based market distinctions.
- Record count alone does not establish demand, scarcity, price direction, or the suitability of any particular comparable.
