The Man from U.N.C.L.E. was an American television series broadcast on NBC from September 22, 1964, to January 15, 1968. It followed the exploits of two secret agents, played by Robert Vaughn and David McCallum, who work for a fictitious secret international law-enforcement agency called U.N.C.L.E. (the United Network Command for Law and Enforcement.) The series is considered ground-breaking and highly influential among some critics. A standard deck of cards is marked with photographic images of the two stars and program logos.
