The 2017 Valentine's Day stamps were selected through a contest. The blue hearts by graphic designer Ari Kivi are ideal for Finland's jubilee year.
"The playful combinations of blue hearts create an end result that captures my mental image of Finnish friendship. The formations of hearts depict different degrees and forms of friendship and caring," explains Kivi.
"Poster design is the art form closest to my heart, but I consider postage stamps to be part of the same category. As it is often said: if it works on a matchbox, it works as a poster. I think that if you were to enlarge them, those postage stamps would pretty much be posters," says first-time stamp designer Kivi.
The Valentine's Day stamps are domestic no-value indicator stamps, and they are sold in a booklet of five stamps.
