Heinecken undertook a similar “guerrilla” action in 1971 with Periodical #5, wherein he printed an image of a grinning Cambodian soldier holding two severed heads on each page of home decor magazines, such as Living Now, and fashion magazines. The original picture, taken by German photographer Dieter Ludwig and published in the February 1971 issue of Time magazine, is a particularly ghastly one among the influx of Vietnam War images published regularly at the time in the press.
