I'm always looking for very old prerecorded cassette tapes, feel free to post any photos of your old ones. I think most started showing up around 1966. My local record shop had these in the cheap box, the Moody Blues is from the 80's, I got it because of the rare label and it cost nothing. The other two are AMPEX Tapes, according to Discogs, they're from 1967! Making them my oldest tapes so far. The Ampex Shells are slightly different, I'm sure little quarks were showing up in the early days that had to be fixed.
nice! yesterday got my oldest in (as of yet). First cassette by Radiola (Philips) from 1966, that's a blank cassette btw...will shoot some pics 2morrow in daylight.....
