Kuvasto Oo! Juha Mäki-Jussila Puistolan peruskoulu, Koudantie 2, 00760 Helsinki Indoor Sculpture Juha Mäki-Jussila’s (b. 1967, Ilmajoki) installation in Puistola Comprehensive School is entitled Oo! It consists of two leaded stained-glass works, one in the window wall of the school library, the other in the window of the dining room. Behind the colourful works, a view opens up into the garden. The artist plays with the shapes of letters in the work. The letter “O” is most prominently visible in the piece in the dining room, whereas the work in the library features fragments of letters that spell out “Puistola”. The work was produced under the Percent for Art programme, and it belongs to the collection of the City of Helsinki, managed by HAM Helsinki Art Museum. At map
