The Batman Begins limited edition DVD set has been making its way to the first purchasers, and with it comes some more viral marketing clues for us to drool over.

On the small USB dongle that comes with the gift set, which contains a number of production images, etc, there is a plaque paying reference to the Gotham Historic Trust. There is also a paying in slip for the Gotham National Bank with username and password scribbled on.

Gotham Historic Trust

Calling the number, 1866 241 1150 as listed on the plaque returns the automated message:

Thank you for calling.

An update to the Gotham National Bank also mentions the trust:

Gotham National Bank downtown is proud to be on the Gotham register of Historic Buildings. The main branch of Gotham National Bank was originally the old 1st Gotham Bank. In 1934, it was sold when the bank closed. The building passed through many hands in the intervening years and was vacant when it was purchased by Gotham National Bank. After several years of restoration under the oversight of the Gotham Historic Trust, the bank was restored and proudly re-opened its doors at 9:00 am on March 7, 1985.

Thanks Pierre!
