The artists might not have originally intended to expose journalism's covert functions under? political and social power structures. Nonetheless, they have achieved it through their work entitled 13 Months in the Year of the Dog and another series of ongoing creations on the theme of role switching between inflictor and victim. From these impressive and counteractive pictures, we are brought back to a humanity that has been expelled and exiled out of our minds by the symbolic power of journalism.
