Are these official? Where do you get the square version? I can only find posters from GOG and Steam. I was thinking about something like this: The square version is just an extension of the poster. But the logo seems smaller in this case. Would it be better if the logo was bigger? Sorry to ask. I can't seem to find a page with guidelines for the images.

Regarding guidelines, should the game's logo on the Poster and on the Square have the same size or should the Square's logo be bigger than the Poster's to account for a bigger image?
