David mentioned he was planning to self-publish this "Grandissimo" book soon.

He raised the money on kickstarter.com (Oversubscribed)
http://www.kickstarter.com/projects/1588383140/publish-grandissimo-the-first-emperor-of-las-vegas

The book is now available on Amazon & elsewhere.

For a drawing of the never-built Grandissimo, scroll to the bottom of the kickstarter page.
Reminds me a bit of the mega-casino complexes built in Macao and Singapore.

Looks like a fun book. I plan to order it soon.
