One of the final works of art created by Andy Warhol was The Camouflage Last Supper, a large silkscreen painting based on the mural by Leonardo da Vinci. It features a black-and-white rendition of the familiar image, obscured by splotches of green, brown, and gray in the pattern of an M81 combat uniform. It’s a strange mash-up of styles but also a fitting metaphor for the life of Warhol, the influential pop artist who cavorted with speed freaks and drag queens and became an emblem of 1960s decadence — and also maintained a Catholic faith that he mostly concealed from public view.
