I'm planning to post here some 'rough' hi-res pictures freshly baked out of my scanner from various cards that I own in different languages. The purpose is to put in light the eventual differences about illustrations cropping, colours and printing quality.
These are ROUGH scans, no defects cleaning process applied on them. They are made at 1200 ppp, they are HUGE, you can download them with a right click and inspect them at full size on your computer in order to put your eagle eye at work !

So let's start with 'Wolf Riders' in spanish, english and french. The only printed official card (afaik) which illustration 'pops' out of its frame :
Spanish : Very good illustration, a bit softer than the english one. Grain on the rest of the card is 'uniform'. The best of all 3 imho.
English : Very good illustration, a bit crisper than the spanish one with slightly more grain. Grain on the rest of the card is not 'uniform' and shows a load of clearer spots almost forming diagonal scanlines. The 2nd place on the podium.
French : A lot of grain on both the illustration and the rest of the card. Colours are slightly more pale. The 'worst' of all 3.
