Few instruction manuals are as effectively designed as the Tigerfibel, designed for the crew of the Tiger tank.

From the Wiki..
Like other manuals designated as Fibel (basic primer), they summarised what the crew needed to know for day-to-day use of the tank, but unlike the typical tedious style of a German tank manual of that period, it is well illustrated in a comic style and much of the text is written as humorous poetry.
The author's knew their audience, with plentiful use of scantily clad ladies.
