Sunday Stamps: The Karst edge

 This week's Sunday Stamps theme is mountains, and I'm going to bend the theme a bit with this Slovenian stamp issued in 2025, as it features cliffs instead. This fascinating and beautiful part of Slovenian topography results from the transition from the Istrían plateau to the Adriatic Sea.

The stamp is labeled EUROMED POSTAL, which is a regional subdivision of the Universal Postal Union consisting of 22 Medierranean nations. The theme for 2025 was 'Resources of the Mediterranean'. The website requires you to be a member, however you can see the top three entries here.

Sunday stamps: Airmail

 Today's theme is aviation, and it made me think of the stamps issued in 2018 to celebrate 100 years of airmail in the USA.

I sent that envelope to Eric in 2018, and you can see the accompanying red version on my previous post about it.
