"Rules of Acquisition" prop in the Star Trek memorabilia museum in Las Vegas.

The Rules of Acquisition were a numbered series of aphorisms, guidelines, and principles that provided the foundation of business philosophy in Ferengi culture. In the mid-22nd century there were 173 rules, but by the 24th century there were 285. Commentaries existed for the Rules. More specifically, this is a nerd ass prop replica of the Ferengi Rules of Acquisition.
