These boxes have fold open front covers with a pocket to hold a catalog of other films. Sorry, no catalogs - they disappeared long ago. These boxes also have a red or black label along the right edge to denote regular 8mm or Super 8mm (regular 8mm has the black labels). Most labels present and intact but they are the first thing on the box to show any wear.
Probably the best quality of all the films and usually featuring only the biggest stars these are generally regarded as the very best.
Earlier films were issued in standard 5 x 5 boxes - see listings in that category.
