Pop art appropriates everyday objects and aesthetics to examine — or embrace, as the case may be — the very culture of mass production and consumption in which they exist. Sinister Pop at the Whitney Museum of American Art is more pointed—a method designers should take to heart. While it wasn’t always obvious how technicolor pop art felt about the ever-broadening culture it represented (Warhol maintained that he sincerely loved mass production and its cultural fallout), the pieces in Sinister Pop usually have a clear target and the mood is angry. They more overtly attack the darker backdrop of ’60s America (today’s too): war, gender bias, racism, labor disputes, segregation, class war, the death penalty. This exhibition, aside from being an enjoyable exploration of the dark side of pop, provides a helpful hint to designers: Don’t bury “the lede” (journalism speak for the key part of a story). If there’s something very important you’re trying to say, make sure you make the message loud and clear. Imagery, tone and text should work together to create a message that’s hard to ignore. Peter Saul attacks the Vietnam War in “Saigon” by making it disturbing to look at, with tawdry colors and vicious imagery. He also includes the text “white boys torturing and raping the people of Saigon.” In “L.B.J” Judith Bernstein takes on a president complicit in that same war war, both visually and rhetorically, by masking his image in steel wool and scrawling attacks against him in writing. Milton Glaser’s United Farm Workers’ protest poster, effectively titled “Don’t Eat Grapes,” says just that front and center, right above a cluster of grapes arranged like a skull. The Whitney wields its substantial pop art holding to show a more varied array of artists than are normally on a pop-art bill and a much darker side of the movement, one that is also an exercise in saying what you mean. It’s worth visiting if only to show that beyond pop art’s tongue-in-cheek, it’s all teeth.
