Remember the first time Darth Vader appeared on screen... The Empire had just captured the Rebel Blockade Runner and were boarding with Stormtroopers. Bang! The door went and through they stormed. A few minutes after the battle, Vader stepped forward.
Here's my playset for the Blockade Runner. It consists of two rooms - the room on the right, is the one where we see Vader for the first time. The playset has a wall in the middle with a door through to the second room. In this second room, here we see Princess Leia load the plans for the Deathstar into R2D2.
I'm looking forward to getting this one printed out and seeing Vader - all contrasted against the white of the space craft. That'll take me back to 1977!
