I thought I would convert the artwork files used in the loading screens in the crusader kings 2 files to a usable file if you want to set on as your wallpaper. All credit goes to paradox interactive for making crusader kings 2 and the artwork. All I did was convert!
Anyway below is a download link to a zip file which contains 8 Wallpapers which by default are 1920x1440 so you should have a nice clear picture.
Download in the attachments below!
