I have a copy of this very rare book by Kenneth Shaleen: http://www.amazon.com/Open-Interest-Kenneth-H-Shaleen/dp/0786309881#_ No pencil, no pen, no highlighter markings -- nothing; hardcover perfect condition. It's absolutely NEW, in 'collector status', it's been in smoke free environment. If interested PM me. Only serious guys, please. Thank you.
