I'm a complete ignorant when it comes to art, but I find it interesting to see pieces of art from different countries sometimes. It gives me a bit better idea about this country's culture and sometimes also history. Unfortunately, sometimes it's hard to find any further information about the artists (like in this case), probably because they're not really known outside their countries.
The only info I could find about this card is that it's a painting called "Maisema" (according to the google translator it means "landscape" or "scenery"). It was painted by Martti Ranttila in 1944 and can be found in the Riihimäki Art Museum.
