This is an audio cassette tape likely released around 1970 by AudioMagnetics Corporation, founded in Gardena, California, USA in 1966. 【Recording Time】 60 minutes (AC60) 【Made in USA】 The back of the box is designed for mailing, with space for a stamp and address (see photo 3). This was found while cleaning out my father's room. ※All three tapes function well. The tapes contain Latin music, Western music, and radio programs (Yo no Shirabe) from FM airchecks in the 1970s. Item will be handed over in person. This cassette tape in its original paper box is a very rare item! I will sell it to someone who is interested. Please refrain from purchasing if you are overly concerned with minor details or are overly sensitive. Thank you for your understanding.
