At first glance Curtain, the work by the Finnish artist Liisa Ahlfors, could be passed without notice. A simple curtain – both a signifier of an inhabited house, and the division between the private and public sphere – is placed on one of several abandoned wooden houses in the town, adding yet another layer to the aspects of city planning, living conditions and the public common. The domestic environment is even further highlighted in the material used for the curtain. Instead of lace, it is made of sour milk applied to the window, which, as the organic material it is, may affect the appearance of the work during the exhibition. Any eventual decay could be understood in relation to rural cities, often suffering from emigration, and the relationship between the centre and periphery in our society as a whole.
