Minneapolis: Minnesota Products, ca 1976 . Floppy vinyl record enclosed in 9½ x 9½ printed envelope; the envelope printed with an illustrated cover and track list; a few short tears and some toning on the sleeve, the contents not inspected as the envelope remains sealed, as issued, though some peeking reveals what appears to be a relief printed card sleeve and vinyl on the inside. From an article in Insider Magazine's July 1976 issue:
