Cloak and dagger world of spies exposed in New York exhibition

are exposed in a new exhibition, the first to be sanctioned by U.S. intelligence agencies.

Hmmm got to wonder about this claim. After all, there's a Spy Museum in D.C. that has been around for a decade:

Pretty interesting stuff! But with all the spies at the UN and the FBI etc all trying to listen in must be like bugging the tower of babble. Collect all kinds of info but from that, where can we actually get understanding and wisdom? Forever a rare commodity.

the first to be sanctioned by U.S. intelligence agencies.

This means a lot is fabricated and/or omitted. That makes the exhibit an act of fiction inspired by real events.
