Got my book in the mail today. Overall, it's pretty good. I'm a bit disappointed to have spotted some editorial errors. On page 106, it claims in the diving bell tintype caption that I live in Springfield, MO. No offense to anybody from Springfield...but I have NEVER lived in Springfield...it should read Pea Ridge, Arkanasas. Oh well...and on the opposite page, p. 107, under a publicity photo of the diving bell, it reads that the diving bell was "the amusement industriy's first simulator attraction." Wrong. It was one of the first ones, but Disney had already done something by then, and perhaps a few other places, too.
Only one other complaint, for my $35, I'd like to have seen more bulk to the book..ya know...a bit thicker, more pictures. But I have got to admit, they could enlarge the book four times and still not have enough photos for me!
I recommend picking up a copy if you can afford to do so. The 50th anniversary year will never pass our way again.
