Actually the photo shown isn't 'Three Brothers' - that's 'Totem Modern' by a street artist called Honet who has painted the heads of various superheroes in groups of 3 on the road pillars all around Kriesau u-bahn station (line 2). I saw Batmam, the Thing, the Hulk, Captain Marvel and quite a few others. Three Brothers is a bit further down and is a similar set of street art paintings also under the roadway but painted by Brazilian artist Speto to celebrate the Amazon. It's pretty cool. And while you're here stroll across towards Messe to see City Lake,
