I love graffitis in memory of 1944 Warsaw Uprising, here are some of them:
"We'll always shed blood for you, Warsaw"
"Because this is my city, marked with blood. Here the insurgents grabbed the weapons, to fight for freedom they came out of hiding. We're proud of our origin"
"Death was the price of the taste of freedom", "63 days of glory"
It makes me so proud to be Polish...
