Ed Roth and Robert Williams still continue to inspire, even at Comic Con, even with R2D2

this is the R2-ME2 Exhibition by Sideshow Collectibles, see about 60 various R2D2s from many artists, in many styles and pop culture references... it's really terrific: http://www.rebelscum.com/2015-Celebration-Anaheim/Star-Wars-Celebration-Anaheim-2015-Sideshow-R2-Me2-Exhibit/
