The German satirical magazine Simplicissimus started in 1896 and continued into the 1940s, despite many law suits from offended people. The Munich-based weekly issued a Colonial edition on 3 May 1904, expressing its opinions of imperialism in Africa.
The amorous French (note the 'half-caste' child) and the greedy Leopold (his African empire became the Belgian Congo in 1908), the numbered giraffes and the smug British suggest that attitudes to African imperialism in Europe were broad.
The sign on the tree says in German 'It is forbidden to dump garbage and snow on this site" (my thanks to Rainer Lotz).
