Auction Catalogue Terms: 'Attributed To', 'Circle Of' and a/f

What 'attributed to', 'circle of' and a/f mean in an auction catalogue, how attribution language moves price, and why the glossary governs.

MODULE_01EVIDENCE

Catalogue language is pricing language

01Auction catalogue terms can look like legal boilerplate, but they carry much of the pricing information in a listing. Whether a lot is described as by an artist, 'attributed to' them or 'circle of' them, and whether it carries the abbreviation a/f, can matter more to its value than anything in the estimate.

02Those phrases are the house's formal opinion about authorship and condition. They are chosen with care because the house's liability, and often any authenticity warranty, attaches to them. Reading them precisely is the first step in reading the lot.

MODULE_02QUALITATIVE

Attribution qualifiers, from strongest to weakest

01Houses that follow traditional British and European cataloguing practice use a hierarchy of qualifiers, especially for Old Master and nineteenth-century pictures. The wording below reflects common usage; the exact definitions for any sale are those in that catalogue's glossary.

02Each step down the ladder is a step away from the artist's own hand, and prices generally fall away steeply. A work described as 'circle of' a celebrated painter is not a discounted version of that painter's work. It is a work by someone else, priced on its own merits and on its proximity to the name.

03Qualifiers also affect recourse. At many houses, the authenticity warranty in the conditions of sale applies to the unqualified heading and is limited or excluded where the attribution is qualified. The conditions set out exactly which statements are covered.

  • The artist's name alone: in the house's opinion, a work by the artist+
  • Attributed to: in the house's qualified opinion, probably a work by the artist, in whole or in part+
  • Studio of or workshop of: executed in the artist's studio or workshop, possibly under their supervision+
  • Circle of: by an unidentified hand closely associated with the artist and of the period, but not necessarily a pupil+
  • Follower of or style of: by a painter working in the artist's manner, contemporary or nearly so, not necessarily a pupil+
  • Manner of: in the artist's style but of a later date+
  • After: a copy of a known work by the artist, of any date+

Signatures, dates and inscriptions

01A related set of terms describes what is written on the work. 'Signed', 'dated' or 'inscribed' generally means that, in the house's opinion, the signature, date or inscription is by the artist. 'Bears signature', 'bears date' or 'bears inscription' generally means it may be by another hand.

02The difference is easy to miss and material. A signature the work 'bears' is one the house is not standing behind. For prints, editions and sculpture, similar distinctions apply to edition numbers, stamps and foundry marks, and those conventions are defined in the relevant catalogue.

MODULE_04QUALITATIVE

What a/f means in an auction catalogue

01The abbreviation a/f is most familiar from UK auctions, particularly general and regional sales of ceramics, glass, clocks, furniture and collectables. It is usually read as 'as found', and some houses use it to mean 'all faults'. In either reading the message is the same: the lot is sold in its current condition, with whatever damage, repairs, missing parts or mechanical faults it has.

02a/f is a warning, not a full description. It signals that the house knows or suspects the lot is imperfect and is not undertaking to list every problem. A clock marked a/f may not run; a vase may be chipped, cracked or restored; a set may be incomplete.

03For a buyer, the practical meaning is that condition risk has been passed across. Inspection at the view, or a detailed condition report with photographs, matters more for an a/f lot than for almost any other, and the price paid should allow for the cost and feasibility of repair.

MODULE_05EVIDENCE

Condition language and what silence means

01Catalogue entries at many houses say little about condition, and the absence of a condition note should not be read as a statement that the lot is in good order. Conditions of sale typically make clear that lots are sold as they are and that condition reports are statements of opinion rather than warranties.

02Condition reports use their own vocabulary. Knowing the common terms makes it easier to read a report and to ask better follow-up questions.

03A brief report may reflect limited examination rather than a clean object. Asking whether the work was examined under ultraviolet light, out of its frame and from the reverse clarifies how much weight the report can bear.

  • Relined or laid down: a painting's canvas or paper has been attached to a new support+
  • Retouched or inpainted: areas of paint loss have been filled by a restorer+
  • Losses: areas where original material is missing+
  • Craquelure: the network of fine cracks in a paint surface, often a normal effect of age+
  • Foxing: brownish spotting on paper+
  • Trimmed: a sheet or canvas has been cut down from its original size+
MODULE_06QUALITATIVE

Read the glossary before the lot

01Conventions vary between houses, between departments and between countries. One house's 'follower of' may be another's 'style of'; some houses do not use the full ladder at all; online-only and regional sales may use shorthand of their own. The glossary, usually headed as an explanation of cataloguing practice or similar, defines what the terms mean for that sale.

02Before bidding on a lot where attribution or condition drives the price, it is worth confirming a few things directly with the specialist: which glossary applies, what the warranty covers for this heading, what the condition report is based on, and whether any scholarly opinion supports the attribution. The catalogue records the house's opinion. The buyer's task is to understand how firm that opinion is, and what happens if it proves wrong.
