It's amazing the things you stumble upon at garage sales. About four years ago I found this tape at one, and after a little hesitation, decided to purchase it. Was it because I knew it was worth money because it had never been released to DVD? Nope. It was because I knew Mario Bava, my favorite director, had a hand in directing it.
Four years later, I still haven't watched it, and probably never will. So my loss is your gain. The case is in pretty good shape, except for an "OK" written in pen in the "Charter Entertainment" banner on the top of the case. I honestly can't say if it works or not, but the tape looks good, so I have no reason to believe that it wouldn't.
This is so ultra-rare that pricing information is hard to come by...currently, there are five copies on another marketplace, with the starting price a whopping $71.99! We're not quite going to gouge you that much, but there's no denying this is a hard-to-find tape.
