My cousin had the same question so I did some research. At first all I was finding was scanned e-books so I thought maybe she was right. Then I finally found that there was a physical copy other than the Library of Congress at a university in Kansas. I think there was another physical copy at a university in England. That made me think perhaps it was real. It would be interesting if someone could go to the university and examine it. On another topic I also counted the number of letters in Ingersoll Lockwood’s name and it’s 17. So interesting!
