Introducing the RetroSuperFuture Andy Warhol Knives Purpureus sunglasses. Designed in collaboration with The Andy Warhol Foundation for the Visual Arts, these sunglasses capture the personal style of the great artist. Known for his iconic looks as much as his revolutionary art, these sunglasses are a contemporary adaptation of a pair that Andy Warhol wore during a period of his life, around the '60s. The design features a wrap-around oversized shape with thick edges and sturdy arms. Warhol's Knives artworks from 1981-82 are designed as an exclusive set of metal decorations on the arms. This version is available in Purple with bottle green lenses.
