According to a news story I saw recently, the official cards are made by the Liberty Playing Card Company, sold here.
I heard on the news today the official cards can be found at centcomcards.com
Notice what they say here:
When I read between the lines, I see a company that is producing high quality reproductions of the cards produced by CENTCOM.
The PDF I gave should print out at about 18x20. Maybe Kinkos could do it if you want a deck?
