My first Christmas card of the season turned out to be a stamp card from Finland showing the 1987 issue while on the reverse were the latest irregular shaped ones. They are of a very traditional style apart from being cut to shape.
Also from Finland came a shaped Moomin stamp accompanied by a shaped Moomin air mail sticker
Then three larger-than-normal issues, one goes without saying - the Postcrossing issue, and the other two are paintings by the Finnish artist Eero Järnefelt: Burning the Brushwood and Forest Landscape.
