Who is Madame Lenormand and why she has nothing to do with our cards

The Lenormand cards are named after the famous fortune teller Madame Lenormand. Is it really their cards? In all honesty, they are not. When these cards were first published, Madame Lenormand was very famous and above all dead. She had died shortly before and what could be more natural than to use this famous name. An excellent marketing ploy. The fact is, Madame Lenormand did not use these cards, their cards are lost, we still do not know what they looked like to this day.
The marketing move worked. The cards were very popular in Germany. They have only been internationally popular in the last 10-20 years and have been experiencing a real hype for a few years because they provide great information.
