## About Johannes Korthals

Johannes Korthals, also identified as Jan Korthals, was a Dutch painter born in 1916 and deceased in 1972. The collected identity records connect the formal name Johannes Korthals with the shorter name Jan Korthals, an important distinction when matching artworks, catalog entries, and auction records. A Dutch-language biographical reference describes him as working in an impressionist style, although the present source pack does not contain a museum or scholarly account that would allow a more detailed assessment of his artistic development. Collectors are most likely to encounter Korthals through paintings and auction-market listings under either form of his name. The available evidence does not securely establish recurring subjects, named series, training, exhibition history, or a detailed chronology. Those details should therefore be verified from catalogues, inscriptions, provenance documents, and accessible institutional records before being used to identify or appraise an individual work.

## Common works and media

The available identity sources characterize Korthals as a painter, so paintings are the only securely supported work category in this source pack. The collected material does not establish preferred subjects, specific painting media, drawings, prints, sculpture, ceramics, posters, editions, or named series. Those classifications should be based on the individual object and corroborating catalogue or auction documentation.

## Market and appraisal context

Appraisal research for Johannes Korthals should begin by confirming that the artist named on a signature, label, catalogue entry, or auction record is the Dutch painter also known as Jan Korthals. Relevant comparisons should use works of the same type and medium and should be drawn from documented public sales whenever those records are available. The collected pack signals an existing body of Appraisily auction records, but it does not expose individual lot details, realized prices, condition, dimensions, dates, or provenance. Consequently, this profile does not support a price prediction. A defensible valuation would require examination of the specific work and comparison with sufficiently documented lots attributed to the same artist.

## 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. This profile is intentionally limited where the collected sources do not provide sufficient detail.
