I just thought I'd share it, since I love Ralph McQuarrie's Star Wars art. It's just a pleasure to look at, not just as a interesting look behind the making of the movies, like concept art so often is. But damn, is it expensive. 250$... I'm not saying it ain't worth it, but I sure can't spend money like that on something like it. Still, a truly great addition to any fan's collection. Which, let' be honest, can't be said about 99% of the stuff that has the "star wars" label on it.

McQuarrie's incredible imagination to draw up worlds and characters played a huge role in making Star Wars a reality. It is expensive, true, but I have no doubt it's an amazing collection of artwork. By the by, you can get it on Amazon for $180.
