Re: Abe Lincoln's Quote
Impressive, but all of these references are circular, with only one real endpoint, the book by Emanuel Hertz. I don't know what his source was, since I don't have access to the book. For the record, I noted this page in passing as I researched this the first time.
Again, quoting a different reference, (scroll down to bottom) there was a letter in 1888, but it was a forgery.
For more, scroll down to page 4 of this document and read from there.
There are plenty of people willing to piss all over corporations, many of them famous politicians. You don't need the Lincoln quote that badly.
