Bob Guccione’s muses manifested themselves as Penthouse Pets. His photography of these beautiful women defined erotic art for the latter part of the 20th century. At one point in time, muses were the Greek goddesses of inspiration in literature, science, and the arts. Without them, Homer would have never written The Illiad, and Euclid would have never had created the Elements of Euclid. Although these two visionaries are long gone, new generations of artists likeJeff Koons and Richard Prince have continued to find their own muses in order to create both beautiful and controversial works of art. For Bob Guccione, his muses came in the form of beautiful women. From Sheila Kennedy to Pia Zadora, these women helped shape Penthouse magazine. With their dazzling personalities and to their alluring figures, Guccione’s muses helped shape 1970s and 80s views on beauty and sexuality as a whole. While it is difficult to determine which of the 1000s of women were the most important in Penthouse magazine history, it is clear that there were a few dozen that were absolutely Bob Guccione's favorites.
