Gruenholtz is renowned for his stunning artistic photography of the male form. In this calendar, he turns his attention to the natural beauty of the erect penis. Even today, this subject matter is considered off-limits for “art.” Gruenholtz reclaims the erection as something worthy of the artist’s attention. His timeless and elegant pictures show erections as they occur throughout the day—spontaneously and instinctively. The photographs in this calendar present erections as extemporaneous events: a pure phenomenon of nature that is artistic, unapologetic and beautiful.
