It might seem suspicious that the Wildlife Park Goldau campaign touting "the zoo without bars" has what appears to be bars separating the viewers from the animals captured. But those aren't a person's average bars. In place of metal is wood. These 'bars' are simply strategically placed trees, which showcases the lush forests the animals are encouraged to roam.
The Wildlife Park Goldau campaign was created by Advico Y&R, an ad agency based in Zurich, Switzerland. The images, which were photographed by Andrea Vedovo and retouched by Alex Herzog of Red Department, capture the feeling of freedom even in spite of the fake bars obscuring a clean view of the animals. It was art directed by Fabian Esslinger with creative direction by Martin Stulz and Dominik Oberwiler.
