I've mentioned before that the National Maritime Museum had put some of its collections online.  Well, I discovered at the weekend that this website by Surface View also has images from the NMM available to order as large-scale wall murals, prints or blinds.

This means that you can have an images from the plans for the Mauretania (1907), HMS Fearless and even the Bounty amoung others on your wall.  They also offer images from other archive collections, museums and photography collections.
