Oldsmobile Complimentary Tape Cartridge

This version is a cassette shell with a soft matte texture around the shell edge. In the top left corner of the cassette shell is a small raised ∆ in a circle. "Made in U.S.A." appears as recessed text towards the right side of the top edge of either side A or B. In the bottom left and right corners of both sides of the cassette shell there are large circles with smaller circles inside. There's a large "0 50 0" in a wide typeface under eleven short vertical hatchmarks, all as recessed text under the timing window. The top left and right corners of the printable area on the shell are very slightly rounded.
