I really like the work of Hanna Konola, who lives and works in Helsinki.
(Magic, a poster for Fine Little Day)
Her palette and the simplicity of the forms I find soothing yet engaging, with a timeless feel to them.
As well as creating prints (in silkscreen and in monoprint), she also does posters and editorial illustrations. If you want to check out more, she has a site, a blog and a shop.
