Hey Maurice. Thanks for pointing out that article in MediaScene on Ralph McQuarrie. Based on the link alone, I found the issue on ebay and just ordered it. It's fascinating to see sketches that haven't surfaced anywhere else, even in that huge (and obscenely expensive) McQuarrie retrospective book that was published about five years ago. There's a new edition of the book on Kickstarter that's much less expensive and features lots of new material, though it excludes his Star Wars art.
