How Much Is Blackboard Worth?

Conclusion: Based on direct comparables from Cy Twombly’s 1966–71 “Blackboard” series, we estimate a fair market value of $45–65 million for Untitled (1968), oil‑based house paint and crayon on canvas, 172.8 x 216 cm (68 1/8 x 87 1/8 in), in the collection of The Museum of Modern Art, New York [1]. This range places the MoMA canvas below the very largest, record‑setting “Blackboards,” yet distinctly above the mid‑tier results for smaller or less optically commanding examples.

Key benchmarks: The artist’s auction record remains $70,530,000 (with premium) for a large 1968 “Blackboard” at Sotheby’s New York on November 11, 2015, a canonical looping‑script composition and near‑ideal format for the series [2]. A closely related 1970 “Blackboard” made $69,605,000 at Christie’s New York (Nov 12, 2014). By contrast, recent strong but non‑trophy Blackboards have sold in the high‑seven to low‑eight figures: $41,600,000 for a 1970 example (Sotheby’s, May 12, 2021) and $38,000,000 for a 1969 canvas (Sotheby’s, May 19, 2022) [3][4]. In November 2023, a 1968 Blackboard from the Emily Fisher Landau Collection realized about $26,800,000 at Sotheby’s, underscoring the breadth of outcomes within this series as scale and composition vary [5].

How those comps map to this work: The MoMA painting is a prime‑year (1968) example from the most coveted phase of the “Blackboard” corpus. Its dimensions (172.8 x 216 cm) are substantial but modestly smaller than the widest, record‑setting horizontals (often around 170 x 270 cm). In the Blackboard group, size, loop density, and visual authority directly influence price; holding scale constant, denser, more rhythmically continuous scripts generally command higher values. The MoMA attribution and early institutional provenance (gift in 1969) signal importance and quality, factors that typically support pricing toward the upper end of a non‑trophy bracket.

Market positioning and scarcity: Trophy‑level 1968–70 Blackboards of record caliber are exceedingly scarce at auction, with few truly comparable offerings since 2015. That scarcity sustains the value of best‑in‑class works and anchors expectations for strong, museum‑grade examples a step below the record tier. Recent anchor results in the $26.8m–$41.6m band for smaller or less commanding canvases provide the lower boundary, while the ~$70m record serves as the upper benchmark for the series’ pinnacle. Given its prime date, major‑museum ownership, and substantial size—yet not the absolute widest format—we place MoMA’s example in a confident $45–65 million range.

Insurance note: Replacement values for institutions commonly reference the top of the comp set and scarcity premiums. For a prime 1968 Blackboard, a notional replacement benchmark near the high‑$80m to ~$100m zone can be justified for insurance scheduling, pending condition review and composition specifics; our indicative figure is provided below, sourced to record‑level comparables [2].

Caveats: Final appraisal should incorporate high‑resolution imaging, a current condition report (matte house‑paint and crayon surfaces are sensitive), conservation history, and full literature/exhibition records, as these factors can swing outcomes within the indicated range.
