Manga - Space Operation - Showa Cassette Tape

This is a rare cassette tape featuring nostalgic Showa-era anime theme songs, as pictured.
As it is an item from that era, the case has some dirt and other imperfections.
We do not have the equipment to test the cassette tapes, so playback has not been confirmed.
To the best of our recollection, these were not sung by the original artists.
Please understand these conditions before purchasing.
The outer sleeve is not included.
Thank you for your consideration.
