The beautiful colours of autumn on the card please me so much that I have in fact posted it before (two years ago) but Sunday Stamps gives me the opportunity this time to show the stamp. I'm showing the se-tenant strip because I think it's both attractive and clever. All four seasons are shown, trees reflecting on water. Not only that, the names SUOMI and FINLAND are shown in reflection on the two stamps and so too the denominations.
Other seasonal stamps I've found have been mainly mushrooms.
From Poland, the Mushrooms in Polish forests series, issued in August 2012
From Taiwan, the Wild Mushrooms series, issued in March 2010
One of a set of 4 values showing Edible mushrooms, issued in September 2013
That made my mouth water so I had mushrooms for lunch, but they weren't wild.
This is a post for Sunday Stamps, now hosted by Violet Sky at "See it on a Postcard!"
