## About Nobuo Sekine

Nobuo Sekine (1942–2019) was a Japanese contemporary artist and sculptor associated with Mono-ha. Library authority records identify him under both his Romanized name and the Japanese form 関根 伸夫, helping distinguish his work across catalogues and databases. IdRef records his birth on 19 September 1942 and death on 13 May 2019, while Wikidata independently identifies him as a Japanese artist. Collectors encounter Sekine primarily through sculpture, exhibition and bibliographic records, and auction listings. His Mono-ha association supplies important art-historical context, but it should not substitute for object-level attribution. For entity matching, his record is linked across Wikidata, Getty ULAN, VIAF, the Library of Congress, IdRef, and RKD. The available evidence is strongest on identity, dates, nationality, occupation, and movement; it is thinner on specific materials, named series, individual works, and detailed exhibition history.

## Common works and media

The strongest collected evidence identifies Sekine as a sculptor and contemporary artist associated with Mono-ha. Sculpture is therefore the safest common-work category for entity matching and appraisal intake. The source pack does not substantiate a detailed breakdown of materials, editions, drawings, prints, paintings, subjects, or named series, so those labels should be applied only when an individual object or auction catalogue supplies adequate evidence.

## Market and appraisal context

An appraisal of a work attributed to Nobuo Sekine should begin by confirming the artist's identity and the basis for the attribution. The collected evidence supports sculpture as the clearest auction category and establishes Sekine's association with Mono-ha, but it does not provide object-level details about materials, dimensions, editions, signatures, condition, provenance, or date. Those characteristics should be established from the object and its catalogue history before comparable sales are selected. Appraisily auction records may provide sale dates, realized prices, and related lots when relevant records are available, but comparisons should account for differences between individual works rather than imply a general price prediction.

## Appraisily data basis

Appraisily artist pages combine public artist-identity research with auction records, auction-house context, sale dates, realized prices, and comparable lots when those records are available.
