The first page of Nicolás Guagnini’s 77 Testicular Imprints quotes Elaine de Kooning: “In a period of self-conscious styles, of statements modified, qualified, organized and carefully bolstered, one finds a large ease and authority in Kline’s manner of painting. The tough masculine thrust present in every scraped surface and bruising brush stroke reveals nothing of theory or dogma.” Positioned opposite this quote is an full color image of the Museum of Modern Art’s “12 Americans” exhibition catalog (in which Franz Kline features) that has been “stamped” with one of Guagnini’s testicular imprints. 76 more imprints follow, with stories, quotes, and images and letters that, for one reason or another, have merited Guagnini’s macho stamp of approval (or disapproval).
