What drives the value of a work by Mark Rothko

Classic period canvases (multiforms) — Large oils on canvas with stacked, soft-edged rectangles from the late 1940s onward are the works that define the market and are treated as major museum-level property, sold almost exclusively with full provenance and exhibition history. Anything presented in this category is examined with extreme scrutiny, since the number of such canvases is small and their locations are largely documented.

Works on paper and acrylics — Paintings in oil, tempera or acrylic on paper, including the darker late sheets, form a smaller but genuinely traded segment; many were mounted on board or canvas after the artist's death by the estate. They are valued well below the canvases but remain the most plausible authentic works to appear in private hands.

Early figurative and Surrealist works — Urban scenes, subway interiors, mythological and biomorphic compositions from the 1930s and 1940s, in oil or watercolour, trade at a clear discount to the classic abstractions. Demand depends heavily on quality and on whether the sheet or canvas anticipates the later style.

Drawings, sketches and studies — Pencil, ink and light watercolour studies, often small and unsigned, circulate occasionally and are treated as documentary rather than decorative material. Value rests almost entirely on documented provenance from the estate or from close associates.

Posthumous prints and posters — Rothko made essentially no commercial print editions in his lifetime, so nearly all screenprints, lithographs and offset sheets bearing his imagery are posthumous reproductions or exhibition posters. The market treats them as decorative objects, with only modest interest for early or scarce museum posters in fine condition.

Rothko rarely signed the front of his mature canvases; when a signature exists it is usually on the reverse, on the stretcher bar or on the back of the canvas or paper, in pencil, crayon or paint, often accompanied by a date, and early works are more likely to carry a front signature. Many authentic works on paper bear no signature at all and instead show estate inscriptions, inventory numbers or annotations added when the estate was inventoried after his death. Serious examination today relies on the painting and works-on-paper catalogues raisonnés, on estate and family documentation, and on technical analysis of grounds, pigments and supports rather than on a signature alone.

• Museum and gallery exhibition posters, often bearing printed lettering that has been trimmed away, are frequently mistaken for original colour prints.
• Offset and giclée reproductions on modern coated or inkjet paper reproduce the soft rectangles convincingly at a distance but show a uniform dot or spray pattern under magnification, unlike brushed and stained paint.
• So-called 'after Rothko' editions issued by publishers, sometimes with a printed or stamped signature and an edition number, are not works by the artist and should not be described as such.
• Outright fakes on canvas exist and have been the subject of well-known litigation; thin, evenly applied colour without the layered, translucent staining and feathered edges of genuine work is a warning sign.

• Classic period canvases of the late 1940s to the 1960s, particularly luminous red, orange and yellow combinations, stand far above the dark late works and the early figurative material.
• Scale and format matter: large vertical canvases conceived as immersive fields are more sought after than small or horizontal compositions, while works on paper trade in a separate and lower tier.
• Continuous provenance from the estate, from the artist's early dealers, or from a documented exhibition history is decisive, as is inclusion in the catalogue raisonné.
• Condition issues are specific to his technique: thin, unvarnished, absorbent paint layers are vulnerable to surface abrasion, discoloured restorations, fading of certain reds, and darkening or cockling of mounted paper supports, all of which weigh heavily on value.

• Photograph the entire reverse, including stretcher bars, any inscriptions in pencil or crayon, inventory or estate numbers, and all gallery, museum or shipping labels.
• Photograph the surface in raking light and take one close-up detail so the difference between brushed, stained paint and a printed dot pattern can be judged, and note whether the support is canvas, paper, or paper laid on board.
• Record the exact dimensions, any edition or plate numbering, and gather every document you hold on how the work entered the family, including invoices, correspondence and insurance or loan paperwork.
