So it's well documented that George Lucas had originally wanted to recreate Flash Gordon, but couldn't obtain the rights and so made Star Wars instead. My project imagines that Star Wars was actually a vintage show, which would have aired sometime in the 50s alongside Flash Gordon, and that it was this show that Lucas obtained the rights to and rebooted in 1977.
Here are a few of the props I've designed so far...
The Falcon

Star Destroyer
A Stormtrooper Bucket
and finally, R2-D2
