I have wrote to the Cartamundi support with question about marlboro deck rarity and price. And they answered me today:

"It looks like a promotional order we once made for Marlboro … it is forbidden for cigarette companies to make advertisement with their logo on playing cards.
So I don’t have any information on this projects.
And because this is promotional deck that mean I can’t estimate any retail price for it ☹ this product was given a way gadget for free.

So definitely this is an collectable item but value of it can tell only a collationer of such items. I can’t help in this matter sorry."

So, i will be really grateful if anyone can give me a clue, how can i find marlboro cards collectors, or how can i estimate this deck.
