Someone printed me a full size set back in '95. I still have them hanging up, though they sustained a teeny bit of water damage during one of my moves. I also have the large scale scan of the original blueprints saved on my hard drive. It would be quite easy to flip the colors in photoshop to make them white lines on a blue background. All you'd have to do is have them printed out at Staples or FedEx or whatever printing resource you have. Heck, I could get my brother's sign shop to print them out onto canvas. However, the original blueprints were actually two seperate sheets of plans. Sheet one was a port side and dorsal view, and sheet 2 was an exploded front view of the ribs, 1/2 of the fore and aft view of ship from the front, and 1/2 a ventral view.
They guy who gave me a printout of the one I have hanging, combined the two sheets into one large single sheet blueprint by cropping out a lot of the dead space and Disney ownership text and stuff. I've been toying with the idea of having both full sheets printed out in blueprint form. to replace my water damaged single sheet.
