But this is really scary: the UKMail reports The Last President, written in 1895, was about a President named Trump.
Ingersoll Lockwood, an American political writer and novelist, wrote two children's books titled 'Baron Trump's Marvelous Underground Journey,' and 'Little Baron Trump and His Wonderful Dog Bulgar,' as well as an ominously titled political tome, 'The Last President.'
FYI you can find The Last President"
and Baron Trump's Marvelous Journey
at Internet archives for free download.
