Some very strong portrayals of Gaelic culture in this image (the Tara broach, the tartan, the bodhrán etc.) but, in fact, this is from the Polish ‘Witcher’ Card Game.
The talented artist was Anton Nazarenko but it aligns with Sapkowski’s borrowing of other culture’s constructs. The naming patterns in the Witcher, for example, often include garbled mixings of Gaelic, French etc.
Great pic, though!
