Go to the link and read about these two books:
Baron Trump’s Marvellous (sic) Underground Journey (supposedly published in 1893)
1900 Or The Last President (supposedly published 1896)
As the article about them says, they boggle the mind (at least if it's true that these books exist, are genuinely from the 1800s and that their story line is as it says in that article). Go to this link and be amazed or not. It's got to be be a hoax - doesn't it - but if it's not and if it's for real then it is absolutely amazing!
All the best,
