Galerie Thaddaeus Ropac is bringing a selection of works to Frieze LA including this Rosemary Castoro, above, work on offer for $200,000.

• Rosemarie Castoro, a pioneer in the context of Minimalism and Conceptualism and a central figure in the 1960s New York avant-garde, is represented with one of her exceptional early paintings Orange Ochre Purple Yellow Y (1965). Long overshadowed by her male peers, Castoro is a revelation to today’s audiences. Her first museum retrospective was at MACBA in 2017 and her solo show at Ropac Paris opens on 21 February.

Other featured artists include Irving Penn, Robert Longo with a new work specifically for this fair, Jack Pierson and Tom Sachs. There will also be new works by Ali Banisadr, Marc Brandenburg, Alex Katz, Imi Knoebel, Jason Martin and David Salle, alongside historic works by Joseph Beuys, Rosemarie Castoro, Robert Rauschenberg, James Rosenquist and Andy Warhol, among others.

• A rare, sought-after silkscreen portrait of Georgia O’Keeffe (1980) by Andy Warhol, which has been housed in private collection for three decades, commemorates the historic meeting in 1979 between the Pop superstar and the doyenne of American modernism then in her 90s.
• Robert Longo’s monumental, larger-than-life Untitled (Harley Davidson) (2018) was created specially for the fair, using charcoal striations to convey the motion blur of a vehicle travelling at high speed.
• In James Rosenquist’s major work Hot Sauce (2005), a plate of spaghetti against the backdrop of an exploding atom bomb.
