Kimmo Pälikkö is a Finnish artist. I discovered him when I saw a postcard of one of his paintings of lighthouses on the Wild Postcards blog (Note: my other blog is about postcards http://www.postcardy.blogspot.com/). Many of Pälikkö's paintings have been reproduced on postcards. According to Pälikkö's website "By 2009, over 1300 postcard motifs of his paintings have been produced and over 85 million postcards of his works have been printed."
There are many examples of his artwork online that can be viewed and/or purchased. What I especially liked about about his website are his books on watercolor painting techniques that can be read online in English.
