So I saw this video on Adam Savage's TESTED:
And he was interviewing Brandon from Prop Store about a series of sketches from concept artist that's worked with George Lucas (who also designed Slave 1). Currently Nilo Rodis-Jamero's sketches are up for auction. Though that's not why I'm posting this link.
From the website:
Rodis-Jamero was a key collaborator with George Lucas on the original Star Wars films. Among his more famous designs are Boba Fett’s Slave I and the Biker Scout. He recently brought his unique insight into the galaxy’s visual language to a series of new concept sketches for vehicles, character and costumes.
'I had fun re-imagining Star Wars and remembering what the designs looked like, and why. Once satisfied, I started sketching alternate designs and rekindling ideas that were dismissed along the way,' said Rodis-Jamero.
If anyone wanted to grab some references to build a few reimagined designs, here's a good opportunity! The images might disappear when the auction ends so grab them now.
