A painting from Cy Twombly’s celebrated “blackboard” series could set a record for the artist at auction. “Untitled” (1970) is expected to fetch between $35 million and $55 million on November 12 at Christie’s in New York. Before being offered to buyers at the auction house’s Post-War and Contemporary Art Evening Sale, the work will be exhibited in London and San Francisco.

Twombly, who is best known for his calligraphic, graffiti-like paintings, executed his “blackboard” series  between 1966 and 1971. Using contrasting lines against a light or dark background, these rhythmic works feature geometric shapes, words, letters, and numbers, calling to mind a classroom blackboard or a pupil’s notebook. With its swirling landscape of loops drawn in white crayon against a dark gray background, “Untitled” is hypnotic, entrancing the viewer with its formulaic loops.
