I don't think it is OOP, but it is not widely distributed outside Sweden. I got mine from a Swedish webside (www.saxo.com). The deck itself is not expensive but shipping costs from Sweden are, so that is why it is not a cheap deck (I paid more for shipping of the deck than the deck itself).
I inquired at Tarot Garden about this deck a few months ago and was told they expected to get the English-language version back in stock eventually. Any deck you order from Sweden will be in the original language.
