The other area of collectability are the original blueprints. One might even refer to this category as the holy grail of Big Loo original drawings. A while back the Hakes Collectables auction website had the following under the hammer. The blueprints below sold at auction for over $5,000. Below is the text and photos from the Hakes auction:
