Micro Collection Bespin Control Room Proof Sheet: Proof sheets like this one are simply boxes that have not went through the final process of being folded and cut into their final, production form. While referred to as "proof sheets", these are essentially finalized product where the text, layout and color are concerned. Major changes to the color, text or layout would have needed to occur before these were produced. Cromalins would have been used for that phase of packaging development. Nevertheless, proof sheets like this are interesting to own, display and examine.
