Postcard sent by Heleen (the Netherlands). It's a portrait of Vincent van Gogh, whose 161st birthday would be today. It was sent with a matched stamp. I love the quote on it:
werkelijk, er is niets kunstzinniger dan liefde voor de mensen
('Really, there is nothing more artistic than loving people'*)
And I have just discovered that I got another stamp of this series long time ago:
*Google Translate dixit.
