Hi coredil
I have a Grimaud TdM deck made in 1930's, which has a blue 1890 tax stamp on the Ace of Coins.
Copyright: ˇ B ˇ P ˇ GRIMAUD ˇ PARIS ˇ
Copyright on major Arcane (except XVI La maison dieu, XVII La lune & XVIII Le soleil),
on all honours, the pips have no copyright
French titles
Very thick cardstock
Background color: beige
Cards: 62 mm x 119 mm
Deck thickness: 40 mm
Back design: The same as that of Dusserre reproduction, but finer & darker.
By the way, I have a copy of Marteau's book, too. It was printed in 1970, but the attached plates are CONVER 1880 cards.
So Coredil, let me confirm one thing:
please check the date on the last page (not the reverse of the front page) of your "00a" copy. Is it really a 1949 printing?
