Cipher Studios is now selling individual non-English Hell Dorado cards.
From their website:
Customers may now purchase individual Hell Dorado cards in either French, German, or Spanish through our web store by indicating which language they would like in the special instructions or order comments section during the order Checkout. Eventually we’ll be putting a section for each language and possibly selling cards through distributor sites. Until we get that up we want to make them as available as possible.
