Thinly Veiled: The Phillips Collection yesterday announced the acquisition of Morris Louis’ “Seal,” donated by the Marcella Brenner Revocable Trust. Brenner was married to Morris Louis until his death in 1962, and the Phillips was one of the first museums in the country to purchase a Louis in 1963. “Seal” work was completed in 1959, and like most Morris Louis paintings, it’s a big canvas with veils of paint poured across its surface. The work will be on view through Oct. 9, 2011. (John Anderson)
