Window Boxes
Photo Boxes were more cost-effective than the Clamshells and now the record companies decided to opt for another more economical solution for the Photo Boxes, a generic, universal sleeve referred to as the Window Box. This allowed companies to manufacture large quantities of boxes that could be used for any artist.
US RCA Cartridges were normally made in White color only, but some made in early-to-mid 80’s can also be found in Grey and Black and are Very Rare to find.
