Artist context
About Bob Bonies
Born
1937
Nationality
Dutch
Also known as
Bob Nieuwenhuis
Bob Bonies is the name used in international library authority records for a Dutch artist born in 1937. The linked Wikidata record is headed Bob Nieuwenhuis, while VIAF groups forms of both names within one personal authority cluster. These stable identifiers can help distinguish the artist in catalogues and auction records where names may vary. The collected sources do not establish a full birth date, death date, artistic movement, training, media, subjects, exhibitions, or named series. A Wikimedia Commons image dated 2021 supplies a documented likeness of the artist. Until fuller museum, catalogue, estate, or official-site evidence becomes available, the biography should remain conservative and should not assign stylistic labels or career details that the present source pack cannot substantiate.
Common works and media
The collected authority sources identify the artist but do not document typical media, subjects, editions, series, or object types. No common category of paintings, prints, drawings, sculpture, ceramics, posters, or other works can therefore be asserted from this source pack.
Market and appraisal context
The collected pack identifies an Appraisily auction-record page but supplies no individual lot descriptions, auction-house notes, sale dates, realized prices, or comparable-sale evidence. This profile therefore does not assign Bob Bonies a dominant auction category, rank artist-specific valuation factors, or claim a price trend. A collector or appraiser should first confirm that the object is associated with the same Bob Bonies and Bob Nieuwenhuis authority cluster. Market conclusions should then be based on documented, genuinely comparable public records rather than on the directory count alone. The market section can be expanded when cited auction-house evidence becomes available.
Auction categories and appraisal factors
Appraisal caveats
- The collected pack contains no lot-level descriptions, sale results, auction-house commentary, or comparable-sale details from which to identify artist-specific valuation factors.
- The supplied auction-directory count should not be interpreted as evidence of value, market direction, scarcity, or a dominant work category.
- Identity should be reconciled carefully because the authority sources associate Bob Bonies with the name Bob Nieuwenhuis.
