This was purchased at the Helsinki Central Post Office over a decade ago. At the time, Marimekko and Finland Post (Posti) often collaborated. It has been carefully stored in a dark place. I am selling it to organize my collection. It is a double-sided card, the type where you write a message on the inside. Rather than using it as a greeting card in its original way, I think it would be nice to separate the two sides, frame them, and display them as interior decoration. 13.4 x 13.4cm
