Artist context
About Yvan Theys
Born
1936
Died
2005
Nationality
Belgian
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.
Auction categories and appraisal factors
Common auction categories
- Paintings
- Drawings and works on paper
- Graphic works and editions
- Sculpture
Value drivers
- Work type and medium should be matched carefully when selecting comparables because Theys worked across painting, drawing, graphic art, and sculpture.
- Edition information is relevant for graphic works when present; the VIAF record identifies Les amants as an edition of 200.
- Documented figurative, geometric, and lyrical characteristics may help distinguish more closely comparable works.
Appraisal caveats
- The collected source pack contains no accessible major-auction-house lot descriptions, realized prices, condition reports, or provenance histories.
- The Appraisily artist page was rate-limited during collection, so its individual auction records could not be evaluated here.
- No price trend, scarcity conclusion, or value range should be inferred from this identity profile alone.
- Authorship, date, medium, dimensions, condition, provenance, and edition details require object-specific examination.
