HERC busted open a couple of boxes that have been sitting in his garage for more than a dozen years. They contained cassette tapes, one of which he featured yesterday. Once he dug most of the mixtapes from the two boxes, HERC discovered 25 still-sealed blank cassettes of various lengths, types and brands. These are HERC's scans of those tapes.

These Sony CD-IT tapes are an attractive blue and come with unique slide cases: clear for 90 minute tapes and a translucent white for the 120 minute tapes.
The Limited Edition TDK SA 90 in the sweet clamshell packaging was one of a bunch bought in bulk from J&R Music back in the late 1980s. No idea what HERC paid for them but they fetch between $20-$60 each according to various auction and collector sites.
