Maybe someone was writing fiction at the time or its a complete forgery made to sell a book or use as an idea in a movie that is coming out. You wont believe how many kids thought or initially entertained the idea that Abraham Lincoln was a vampire slayer when that movie came out a few months ago...remember standing in line when it first came out and all the young kids asking their parents if Abraham Lincoln had really slain vampires or not...sad and comical at the same time
Oh, rats. I liked “Abraham Lincoln, Vampire Hunter” much better than the unfictionalized version!
