The Witcher originated as regular novels. But due to its popularity, comic book versions were also created to offer different ways of experiencing the story. So, it's both, depending on what you consider first or prefer.
The main distinction lies in the coverage of the comic's covers. A full cover comic takes up all the available space for art, creating a more impactful and potentially complex display. Regular comics, on the other hand, may have a more conventional cover format with less extensive art and maybe more emphasis on titles and summaries.
Minnie Mouse can be seen at Comic Con on certain occasions. The decision for her to be there might be based on licensing agreements, fan demand, or promotional strategies. But it's not a guarantee for every Comic Con event.
You just need to visit the comic shop frequently and build a good relationship with the staff. Buy comics regularly and show your enthusiasm for their products.
