In the middle of the Art of Star Wars exhibit stood a gigantic Millennium Falcon model. Different scales of Millennium Falcon models were used in special effects photography, but this particular one was used for closeups and must have taken weeks to build.
The ship is about as large as the Toys R Us Millennium Falcon store display (about 6 feet by 8 feet).
Here's a side view of the Falcon. As you can see from this angle, the ship is very sleek in design, although that is not always apparent on screen.
