I’ve been seeing this around various parts of Rome for a while :
From far away it looked kind of like a helmet from a fire-station.
Looking closer, it looks like the classic game, Space Invaders.
They may be hard to spot at first, but once you’ve spotted one, you’d be looking out for more!
Doing a quick search online reveals that all these are artwork which is done by a street artist, Wunderkammern. How cool is that? I love street art 🙂
