This update may be coming a little late, but if the old saying "better late than never" was ever appropriate, this would be it.
According to the official OPX blog, there will be a special Ralph McQuarrie Art exhibit at Star Wars Fan Days III.
"The Art of Ralph McQuarrie will premiere a gallery showing of several dozen never before seen original Star Wars illustrations and film work from the artist's personal collection. A variety of books and signed prints will be available for sale."
Obviously the complete programming schedule for Fan Days III has not been finalized/released yet. But I think it is safe to say rignt now that this exhibit will be one of the best, if not the best, events of the entire convention.
