1970s Scotch Dynarange C90 Audio Cassette

I don’t have a date of purchase for this blatantly very old Scotch Dynarange tape, but there’s one recording on it featuring me as a child, with kids I knew at junior school. The case design ties in with that shown in the 1971 to 1973 stock on http://vintagecassettes.com/, and there’s nothing to contest the fact that my Mom would have bought the cassette during that period. The recording of me as a child wouldn’t have been as early as that – it’s more like 1975 or 1976 I think. But this is a retro cassette, good and proper.
