Cornelius Vanderbilt II mansion NYC

I've been searching for some new links and photos while I watch "Ghost Adventures" on the Travel Channel - my power was out earlier so I'm catching the reruns.

Here's what I've found so far:

Vanderbilt 1

Vanderbilt 2 (scroll almost halfway down the page to view the picture)

Vanderbilt 3 (scroll down to post #5 by The Charioteer - has three pictures of the house)

Vanderbilt 4 (first pic is of a fountain with the Berdorf Goodman department store behind it (where the house used to be) and the one below it is of the house behind the same fountain)
