What drives the value of a work by Yayoi Kusama

Infinity Nets and early paintings — Large canvases from the Infinity Net series, the New York years and the later Dots Obsession and My Eternal Soul paintings form the top of the market and are traded internationally with close scrutiny of exhibition history. Works of this kind are normally accompanied by a registration card issued by the artist's studio, and their absence severely limits saleability.

Pumpkin sculptures and soft sculpture — Three-dimensional pumpkins in bronze, fibreglass or lacquered resin, accumulation objects covered in phallic protrusions, and mirror-room related works are highly sought, with monumental outdoor pumpkins at the summit. Small painted-metal pumpkins also exist in numbered editions and are treated as multiples rather than unique works.

Works on paper, gouache, collage — Unique drawings, gouaches, pastels and collages from the late 1940s and 1950s Japanese period, and from the New York years, are strongly collected and often smaller in format. Later signed drawings on paper circulate steadily but at a clearly lower level than the paintings.

Signed screenprints and lithographs — Kusama has produced a very large signed and numbered print output since the late 1970s, mainly screenprints of pumpkins, nets, flowers, hats and shoes, published in small editions. The market is liquid but highly subject-dependent, and unsigned or unnumbered impressions are treated as decorative items.

Merchandise, posters, licensed objects — Exhibition posters, dotted pumpkin figurines, plates, plush objects, skate decks and collaborations with fashion or design brands circulate in very large numbers. These are handled as design or memorabilia, not as original art, whatever the printed dot motif suggests.

Kusama generally signs in the lower margin or lower corner, in pencil on prints and works on paper and in paint or ink on canvas, using either her romanised name or her name in Japanese characters, frequently adding the title and the year; canvases are usually signed, titled and dated on the reverse, occasionally with a small dot or net drawn alongside. Prints are additionally numbered in pencil, with annotations such as A.P., E.A. or H.C. for impressions outside the numbered run, and many were issued through Japanese publishers whose blindstamp or printed reference may appear. The studio in Tokyo issues a registration card with a photograph of the work for paintings, sculptures and unique works on paper, and this document is now effectively required by the trade; no independent foundation or committee is widely recognised in its place.

• Offset or giclée reproductions of pumpkins and Infinity Nets, sometimes with a printed signature in the image, are frequently mistaken for the hand-signed screenprints, which show pencil signature and numbering in the margin and dense, slightly raised ink layers.
• Exhibition posters from museum retrospectives and from the mirror-room shows are reproduced on a huge scale and are often framed and sold as prints, though they carry printed text, gallery or museum credits and no pencil annotation.
• Fake paintings and gouaches are unusually common for this artist, because dots and nets are easy to imitate, and the decisive test is not the look of the surface but the existence of a studio registration card and a traceable chain of ownership.
• Licensed pumpkin figurines, tableware and brand collaborations bear the artist's printed name and a moulded facsimile signature, and should not be confused with the numbered painted sculpture editions issued by galleries.

• The New York period and the earliest Infinity Nets, along with the late 1940s and 1950s Japanese works on paper, carry a premium over the abundant later production.
• Among the recurring motifs, pumpkins and Infinity Nets are the most in demand, while flowers, shoes, hats and faces from the print series are less sought after, and yellow-and-black pumpkins outperform other colourways.
• Scale matters sharply, as do edition size and status: small print runs and early editions are preferred, whereas the large editions issued in recent decades are plentiful and easily compared.
• Condition problems typical of the medium weigh heavily, namely light-fading and paper toning on screenprints, mat burn and cockling on works on paper, and scratches, chips or yellowing on lacquered fibreglass and resin sculptures.

• Photograph the signature area in raking light at close range, so that pencil strokes can be distinguished from a printed facsimile.
• Photograph the entire reverse, including stretcher bars or backing board, the edition number, any publisher blindstamp, gallery or exhibition labels, and any inventory numbers.
• Gather and photograph the studio registration card if one exists, together with invoices, correspondence or catalogue pages showing where and when the work entered the family.
