The fact that it's published by the Swiss company AGMüller / Urania. Most of their decks are printed in Belgium by Carta Mundi, I think, but that's only the printer.
This one (0913866156) is the large size but does not have three versions of the Magus.
I've never seen this one (1572815108). It must be a new one. It's a large version with three versions of the Magus. It looks like it also has a color spread sheet which the other one doesn't have.
