A recent Ukraine Post stamp had one million copies made and very quickly sold out. The stamp is based on an actual event on the first days of the 'Special Military Operation' (aka Russian Invasion), and was popular on the news everywhere.
A Russian warship (the cruiser 'Moskva' (Moscow), their flagship in the Black Sea Fleet approached an Ukrainian coastal island. And they sent a radio warning to the defenders, giving them a chance to surrender.
The Ukrainian special forces operator responded, telling them to buzz off in more graphical terms.
The UA stamp shows the island, the soldier giving a Russian ship the finger.
I understand you might not be able to reproduce their design, but a related stamp could be interesting. And if sold as a Premium Stamp (either 50 Coins, or a special 100 Coins price), with proceeds going to the relief effort to the displaced people in Ukraine, this could help and allow us in the Slowly community to show solidarity.
I made a post on Reddit with a more detailed story. And there's also the aspect that the ship in this event was sunk by Ukrainian missiles recently.
