An appraisal relies on identifying the correct market for the artwork and analyzing verifiable data from relevant auction houses, retail galleries, and recognized databases. We do not invent market data or imply that inaccessible private-sale data is routinely available.
Paintings, works on paper and mixed media
Oil, acrylic and mixed-media paintings, together with drawings and watercolours on paper. We analyse relevant auction records and publicly verifiable retail evidence to develop a credible value opinion for the stated purpose.
Evidence often required:- High-resolution images of the front, back, and signature.
- Medium specifications and exact dimensions (unframed and framed).
- Provenance (ownership history) and exhibition records.
Sculpture and installations
Bronze, stone, wood, and contemporary installation works. Valuations account for edition size, casting date, foundry marks, and shifting market tastes for three-dimensional works.
Evidence often required:- Detailed macro photography of foundry marks and edition numbers.
- Exact weight and dimensions.
- Original acquisition documents or certificates from the publisher.
Original prints and editions
Lithographs, etchings, screenprints, and other editioned works. We establish value by referencing catalogues raisonnés and identifying the specific state and edition of the print.
Evidence often required:- Close-ups of edition numbering, artist signatures, and publisher blind stamps.
- Sheet and image dimensions.
- Condition notes regarding margins, toning, or mounting.
Photography and new media
Vintage and contemporary photography, digital media, and video art. We consider printing processes, vintage status versus later prints, edition sizes, and condition specific to photographic materials.
Evidence often required:- Details on the specific printing process (e.g., silver gelatin, archival pigment).
- Date of the negative and date of the print.
- Information on mounting, framing, and artist stamps.
