On the cover, Los Prisioneros appear on Line 2 of the
Santiago Metro going to San Miguel. In the original photo, Miguel appears standing, with his arms behind his head, looking into space; sitting in front of him, Jorge and Claudio looking at the camera. Jorge with an ironic smile and Claudio laughing happily. In 1987, during a promotional tour in
Buenos Aires, Argentina, the guitarist recounted in his book
Los Prisioneros: Biografía de una amistad, that the album cover had a different photo. "He looked the same except for one small detail: I didn't appear laughing," he said. As the representative of the group —Carlos Fonseca— explained to him, the original had been lost, so they decided to look for the one closest to the sequence —taken a second before or after the other— to replace it. "It was almost the same, only in this one I had a lost look," Claudio explained. Later, in Chile, the photograph was also changed, then, when Pateando piedras came out on CD, the photo where Claudio was smiling came out, however, shortly after they replaced it again with the other one. "Summarizing, the story goes like this: Kicking stones was released in September 1986. But already in April 1987 there was another photo. Then in 1991 it appeared. Then, in 1992, it got lost again," he concluded. The session at the Metro was in charge of Jorge Brantmayer, inspired by the techno "wave" that the band took with their publicized Casio synthesizers and Simmons de Tapia drums. The vinyl edition, which could only be purchased at Fusión, had a low-angle photo of the band on the back cover in front of a high-voltage tower, 40 kilometers south of Santiago, on the way to
Rancagua. Los Prisioneros never liked the photos of the Metro, according to Fonseca. At first Jorge suggested to Carlos that the three of them appear in the photo in a huge green field, and that they could be seen walking in the distance, however, EMI rejected the idea, since, according to them, it was going to look like a
Los Huasos Quincheros album. == Release ==
