## About Yvan Theys

Yvan Theys (1936–2005) was a Belgian painter, draughtsman, graphic artist, and sculptor. He is associated in Dutch-language biographical material with the emergence of new figuration during the 1960s, alongside Alphons Freymuth and Reinier Lucassen. That context joined recognizable figures with expressive handling, flatter pictorial spaces, geometric signs, and lyrical elements. Theys nevertheless worked in several media, so his name may appear on paintings, drawings, graphic editions, and sculpture rather than on a single uniform type of object. Authority records maintained through Wikidata and VIAF establish his identity and lifespan and connect him with additional national-library identifiers. For collectors, this breadth makes accurate medium identification especially important: a painting, a work on paper, an editioned graphic work, and a sculpture require different comparisons. The available source pack supports his basic identity well, although its art-historical detail relies mainly on a secondary biographical source and should be treated as a starting point for further scholarly research.

## Common works and media

Collectors may encounter paintings, drawings and other works on paper, graphic works, editioned prints, and sculpture attributed to Yvan Theys. Secondary biographical material connects his 1960s work with recognizable figuration, expressive treatment, geometric signs, flatter backgrounds, and lyrical elements, but these characteristics should not be assumed to appear in every work. Graphic objects should be checked for a signature, edition notation, technique, and publisher or printer information.

## Market and appraisal context

A work attributed to Yvan Theys should be compared with records for the same medium and a similar type of object. Paintings, drawings, graphic editions, and sculpture belong to distinct comparison groups. For an editioned graphic work, the edition size, impression number, signature, and printing details should be recorded; VIAF, for example, identifies one titled work as an edition of 200. Date, dimensions, subject, attribution, provenance, and condition should also be established from the object and its documentation before auction results are interpreted. The collected pack did not provide accessible lot-level descriptions or realized prices, so it does not support a price prediction or market-trend claim. A defensible appraisal requires closely matched public sales and object-specific evidence.

## Appraisily data basis

Appraisily artist pages combine artist-identity research with auction records, auction-house context, sale dates, realized prices, and comparable lots when those records are available. Identity evidence and object-specific market evidence are assessed separately.
