Tschabalala Self has Trafalgar Square. "Lady in Blue" went up on the Fourth Plinth today — the most-seen sculpture commission in Britain, held for two years — and it arrives for an artist already in MoMA, the Guggenheim, the Whitney and the Albertina at 36. That combination of collection depth and mass public visibility is the profile that moves a Growth-tier painter toward Value. Elsewhere, sellers are reading the calendar: Sotheby's opens a 140-lot, roughly $10M Lichtenstein Collection sale on October 7, weeks ahead of the Whitney's Lichtenstein blockbuster, and the Met has taken two Alison Rossiter assemblages of expired photographic paper into its collection.
Tschabalala Self's "Lady in Blue" goes up on London's Fourth Plinth, while Sotheby's times a $10M, 140-lot Lichtenstein sale to open October 7 ahead of the Whitney retrospective.
Tschabalala Self unveils "Lady in Blue" (2026) on the Fourth Plinth in Trafalgar Square, Britain's most visible public sculpture commission, on view two years
The Fourth Plinth puts her in front of millions of people for two years, and the primary market for her paintings is already tight — expect gallery waitlists to lengthen rather than prices to sit still.
artist milestone · Growth · Tschabalala SelfSelf's work is held by MoMA, the Guggenheim, the Whitney and Vienna's Albertina, with prior institutional solos at the Hammer and ICA Boston
Four Tier-1 collections plus two museum solos before 40 is the institutional base that makes a public commission stick instead of reading as a one-off; existing holders have no reason to sell into the attention.
museum acquisition · Growth · Tschabalala SelfThe Metropolitan Museum of Art acquires two works from Alison Rossiter's assemblages of expired photographic papers
A Met acquisition at 86 is the kind of late validation that reprices a photography market slowly and durably; the assemblages, rather than the single sheets, are now the works with institutional precedent behind them.

A Duchamp shortlist reliably pulls French institutional buyers in, and he already has Madagascar's 2019 Venice pavilion behind him — the win would be the repricing event, the shortlist is the time to look.

Richards made sculptures linking aviation to Black freedom and died at 38 in the North Tower, where his studio and much of his output were destroyed; what survives is held largely by institutions, and the honest position here is attention to the work rather than a market thesis.
