I found this line on his website:
"6. Tarot 1900, 22 cards, by Simply Red Books, Vancouver, expected date of release 2008"
I found a website for Simply Read Books and sent an email to them asking for a release date, just now. They have children's books and some are illustrated by Iassen Ghiuselev. I did not see this tarot on that site yet. It's not at Amazon yet as a pre-order either.
Thanks for the photo. This is the first I've heard of Tarot 1900. I can only see very small photos at his site. When I click on one, I get a white square.
