So this is one Page from a comic i am currently working on about the Kolonialschule in Witzenhausen. Yes, there is this village called "Witzenhausen" and there was this school, teaching the future "culture pioneers" how to sow and harvest in exotical foreign countries. These days the former colonial school is now an institute of tropical agriculture (http://www.ditsl.org)
We gained access to the local archives and rummaged through the files of students, teachers and staff.
My Comic is set in the early 30's and deals with two students of the colonial school.
