Happy Collection (2012) is based on the value system that speculates a difference between the personas of a hoarder and of an art collector. The former collects invaluable objects, while the latter collects precious ones. In fact, hoarding suggests being free from the material use-value of objects. Being an artwork, this little collection of Deniz’s own trash becomes valuable in the system of art, even deserving documentation and valuation through identification with numbers. These hoarded objects gain a new value when they are defined as an artwork.
