differences among books in various nations?

[king of nowhere]

I ordered my copy of arcanum unbounded from the british provider and I wanted to make sure it has all the illustration it should have. In my version there is an image at the beginning of every story, and one figure of the star system at the beginning of each star system, and nothing else. I thought there was also supposed to be a star chart? I am suspicious because I've seen the italian version of words of radiance and it completely lacks the splash page of shallan, so I figured maybe some british editor also did cut out some image.

So, can someone confirm that I have all the pictures I should have, or if my copy misses something? Thanks

I only have the digital version, so I can't speak for the differences in the hard copy. That being said, the images are all available on Brandon Sanderson's website in the Artwork > Arcanum Unbounded section.

As far as I know US version has additionally star char illustration. And its in color (same like planetary systems illustrations)

I have UK version too and indeed it lacks start chart compared to US version.
