The Berlin Mural Fest was a big Street Art Festival where 20+ Murals were painted over 2 weeks in May 2018 in Berlin.

We painted in 3 days this 20x30m wall in the Lehrter Strasse in Berlin Moabit, a concept that Ben painted in Berlin Tiergarten in 1975 which was the first artistic mural in West Berlin. The old production of Ben is going to be hidden by a brand new office complex being build in front, so in collaboration with Berlin's Kultursenat and the Dixons we were able to "transplant" Ben's mural by painting it brand new on another location.
