I'd never really paid much attention to this line of collecting before, but lately I've picked up a couple of the older costumes and have noticed there's quite a few variations to both the packaging and costumes themselves. Does anyone know of a comprehensive list that includes box and costume variations, etc? Box variations include blue box white or blue logo, orange generic w/ and w/o ESB sticker, ESB, and ROTJ; costumes vary in print quality, materials used, and of course the Return/Revenge variations). I'm thinking that if such a list doesn't exist, it could make a cool project to tackle for Halloween this year
