1981 / Slave 1 from Bespin Diorama
Unfortunately, we only have two shots of the Bespin diorama from the 1981 showroom. And they're only detail shots, not ones that show what the entire thing looked like. As you can see, this one depicts a few figures surrounding the Slave 1 vehicle toy. All these items are placed on a platform. The platform has been cleverly extended into the two-dimensional background by means of some illusionistic painting.
