This German brand was the first one to produce three series you are going to discover. They were brought back by:
Dietl, Dohla, Düka, Schipka and Schulter.
Except for the Grimm Brothers tales, you must know that the morality of Max and Maurice and of Peter Struwwel is today still used by pedi-psychiatrists in Germany.
