I give a shit. You decide how much it is worth.
Moving from this English idiomatic statement, the project aims at establishing a dialogue between artist and public on the material and immaterial value of her work. The meandering questions that inform the work revolve around the meaningfulness of socially aware and socially engaged art, the role of the artist as an agent of political sense-production and eventually the capacity to talk to professional as well as non-specialist public. 
The work will be realised as a public intervention in the urban space and as a physical presence in an exhibition location.
In the latter case one single piece will be exposed in the context of a broader collective exhibition – which topic I can imagine to be any socially relevant one - and will be made available for public estimation, not only aesthetic but also monetary. During the first weeks of the Biennale the public will be asked to give their price for the exhibited piece and will be able to actually purchase the piece. During the last few weeks, if the piece gets sold, instead of the actual piece, the list of offers and the contract will be displayed.
In the second case a considerable amount of pieces (a hundred or more, according to the specifics of the location), labeled with work's info (artist name, year, material, etc. but no contact info) will be left in the public space as an act of public gifting.
