After comparing the PDF proof that Amazon generates versus what is printed in the book, I am confident that the content is comparable. After making some formatting changes, mainly on the cover, I ordered a 2nd author’s proof to make sure that the cover image lightening and image alignment were as I wanted them. The first author’s proof showed me that the book cover was too dark and there was a portion of the sky that was at the top-left corner – very distracting.
On the most recent author’s proof, you can see substantially more detail and more of the Sno-Train than in the first edit. Much improved.
