Anonymously uploaded and designed to disappear automatically once they’ve served their purpose, these pictures are not traceable or visible on the Surface Web; they lead a transient existence exclusively on the Dark Web to illustrate drug ads. The Iceberg presents a selection of these photographs printed in invisible ink. Otherwise invisible and inaccessible, they can only be viewed under ultraviolet light – the same light real-life drug enforcers use to look for traces of drugs.
