“When you think about it,” Andy Warhol once said, “department stores are kind of like museums.” That statement dovetailed into Warhol’s artistic practice, which saw him constantly pulling consumer culture into art. To celebrate his unique vision, Tate Modern has organized a comprehensive Warhol retrospective, which is now available online as a guided tour by curators Gregor Muir and Fiontán Moran. Included are 25 works from “Ladies and Gentlemen,” Warhol’s portraits of black and Latinx drag queens and trans women, a series that hasn’t seen light in over 30 years. —E.C.
