Came across this comic strip at Dongguan, Guangdong Province, China train station. This is the first of the famous German comic strip, Vater und Sohn (translated Father and Son) by Erich Ohser.
Erich Ohser was blacklisted and arrested by Nazis in 1944 for political cartoons and commited suicide on 6 April prior to his death sentence.
See Wikipedia for further information on German comics and Vater und Sohn websites.
The comics is without dialogue and only with title (i.e. if the china version I have is accurate), colored only for the chinese version (original, black and white). The gags are simple and down to earth but not something I can quite identify with.
