Art: consider both image and object
Art encompasses many forms of expression. Paintings, drawings, prints, photographs and sculpture are common objects in antiques and collecting. Describe a work through its materials, technique, subject, authorship and history. These facts answer different questions: who created the image is distinct from how this particular object was made.
Painting: Harriet Backer’s Blue Interior
Harriet Backer’s Blue Interior of 1883 is catalogued as oil on canvas, NG.M.02582 at Norway’s National Museum. Fellow painter Asta Nørregaard was the model, and the picture was painted in Paris. The museum explains how daylight affects the room’s colours. The title does not mean the room itself is blue. Subject, light effects and material explain different aspects.
Prints: the image and the individual sheet
Prints can exist as multiple impressions, states and variants. MoMA’s Louise Bourgeois catalogue distinguishes the composition from individual sheets, and artist from printer and publisher. It also records additions made by hand. Examine a print as an individual object: a familiar image alone does not establish its technique, edition or authorship.
Artist, printer and publisher
MoMA catalogues Paddle Woman, state II of 2006, as a soft-ground etching on paper. The recorded sheet is numbered 9/19, accession 247.2011. Louise Bourgeois is the artist, Wingate Studio the printer and Osiris the publisher. The catalogue notes slight differences in wiping and sheet size between impressions. An edition therefore does not make every detail identical.
Sculpture: from model to finished work
Gustav Vigeland modelled the Monolith at full scale in clay in 1924 and 1925. The model was cast in plaster, and stone carvers transferred its form to a single granite block. The Vigeland Museum retains the plaster model and explains the use of measuring points. Modelling, plaster casting and carving are different stages. Model and finished stone sculpture share a project history but are different objects and materials.
Authorship and documentation
These examples show different working methods, from nineteenth-century painting through twentieth-century sculpture to more recent printmaking. They provide comparisons, not a formula for attributing unknown works to the same artists. Read about artist signatures when interpreting names and inscriptions. Assess a signature together with the whole work and its documentation.
Record materials and technique as precisely as the evidence allows and mark uncertainty. Retain invoices, catalogue references and ownership information. Describe damage and repairs before assessing price. Age, a famous name and an appealing subject do not automatically establish investment value. For possible intervention, read about conservation and restoration. Browse art at OBA and read the information about each work.
