Here's a book uploaded by an auther named "Anon" on July 19, 2017
Baron Trump's Marvellous Underground Journey Kindle Edition
Note that a reader gave it a negative review "Book pages are obviously xeroxed from another source. A number of the pages are missing the first and last lines, some have either the top half or the bottom half copied. Some pages have such large inks blots on the page that entire lines are unreadable. Last line of the book stops in mid-sentence. I bought this as a gift for my daughter, but it is totally unpresentable!!"
Then there's the 3 book bundle. It's uploaded by Amazon services.
The Kindle Optimized eBook is a Collection :
*****Travels and Adventures of Little Baron Trump and His Wonderful Dog Bulger
***** Baron Trump's Marvelous Underground Journey
*****The Last President (or 1900)
Apparently there are lots of printing errors in this copy too:
