Ended up back at Bülowstraße again, and spotted a couple more bits of amazing graffiti that were tucked away. There's more around there I intend to photograph, just need to get some time to do so. Anyway, without further verbage, here is what I saw.
There is an absolute tonne of amazing street art around this city, I don't think I'll ever be able to capture more than a fraction of a percentage of it. Still, I'll keep trying to record as much of it as I can!
