I don't know if that's good news or bad news, Remaniox. Good news that we are on the same page, but bad news as far as your chances of finding this deck I'm afraid. This is not the Egyptian-themed Miss Cleo's Tarot Power deck available by the truckload on eBay, although I have come to the conclusion that the artist is the same (see the JF insignia on both decks-J. F. Lambert no doubt)
I don't believe this would have been sold as a deck. The cardstock is very flimsy, the corners are square, and each card has the number printed on the back. More likely it was used only for promotional purposes, or perhaps when someone requested a reading, the cards were sent along too.
I would be very interested if anyone has more information on these cards.
