P. Boiteau d'Ambly ...
"Wicked Pack of Cards" informs about him p. 214-15, 224, 226 and 288n12. P. Boiteau d'Ambly somehow invented the Gypsie theory.
What DDD didn't tell: He wrote about Mazarin and Louis XIV under playing card aspects. I took for the moment only a short look, but I definitely discovered some material, which interests me. Also he has nice pictures of some cards. And the book has about 300 pages.
I found it online:
