SEX-Madonna, 1992. Japanese edition, with mylar bag.

There are a few important things to consider when talking about SEX.
1: It was banned in several countries, including Ireland, Singapore, India, Argentina, and a few others, for its obscene content. Many stores worldwide refused to stock it regardless.
2: It is the greatest-selling coffee table book of all time. selling out of its original print run of 1.5 million copies in only a few days.
3: It is still the most in-demand out-of-print book of all time. A sealed copy goes for 500-2000 USD.

Obviously, this one isn't sealed, so it's much cheaper.

Originally sold in a printed cardboard box within a mylar bag alongside a spoken word version of her single 'Erotic' on a CD. This copy only has the unsealed mylar bag. No dings or scratches.

Spiral-bound in brushed aluminum, 130 pages.
