Receipt Cases, and Receipt Books revolved around the theme of creating a data double by collecting, assembling and reassembling personal data artifacts.  Given that our society’s heightened surveillance practices and technological marketing strategies increasingly impinge upon our personal privacy, I have diligently replicated their practices by obsessively collecting the artifacts left in the wake of my consumer trail as I navigate both public and private systems and infrastructures; not as an attempt to ‘cover my tracks’ but rather, to create a fuller, more complete data double of myself.  As governments and marketing agencies increasingly collect our data, our bodies, as data doubles, are made vulnerable in new ways.
