[2010] Recreation Signs (Duck Rabbit) consist of generic and custom-designed alodine-coated aluminum signs. Three of the signs conform to the standard symbols used by the National Park Service, U.S. Forest Service, and State Parks to mark designated trailheads. The other two signs feature the ambiguous figure of a duck-rabbit. The figure has been used in psychological research at least since the nineteenth century to demonstrate that perception is more complex than an automatic response to pure visual stimuli. I first learned of the duck-rabbit symbol by reading Ludwig Wittgenstein’s book, Philosophical Investigation (PI), in a passage discussing perception and knowledge claims. The duck-rabbit shape is based on Wittgenstein’s drawings reproduced in the PI and also found in his notebooks. Despite their iconic standing, reading the signs becomes a highly subjective, interpretive process. Each sign is 24" x 24".
