English Ice Age was first released in June, 1995; the foreign languages are all dated 1996. The
copyright lines of foreign Ice Age cards are slightly smaller as normal and the C in the (C) symbol is serifless. The only other sets with these were the Introductory 2-Players
Set, Japanese 4th Edition, and foreign Alliances.
German Ice Age was also released as a Gift Box. English Ice Age had a vast number of print variants. The existence of corrected versions of regular misprints in many languages suggest that there were two print runs.
Ice Age was the only set for which artist proofs in five different languages were given out, for all except German. Unfortunately, I wasn't able to
find even one so far.
