Berlin Tiergarten S-Bahnhof. An office block is being built in front of the mural that has been visible for many years from this platform.
This link will take you to my photograph of the same scene from 1980.
Additional: I just found the following in an article about disappearing street art in Berlin by Philip Oltermann on The Guardian website.
– A real estate developer is building his new offices at Tiergarten station directly in front of Ben Wagin’s so-called Weltbaum or “world tree” mural, a composite of several artists’ paintings warning of the threat of environmental destruction.-
