Kmart 90-Minute Blank 8-Track Cartridge

This blank 8-track cartridge was sold by Kmart likely sold between 1969-1990. The 8-track cartridges were used to record uninterrupted music/recordings and were the predominant piece of technology when it came to compact cassettes.  The design system and packaging of these cartridges were used to quickly describe the capacity of the 8-track, also with space to write identifiers for the recording on the cartridge.
