Secret Courier (7328-1) was available on a hard to find 1975-76 card. In the tradition of the earlier Secret Agent set, this much reduced set consists simply of a shirt and pants in two shades of brown, black boots, and the briefcase fitted with pistol and recorder from Secret Agent. The set is generally found with a black pistol rather than the silver luger shown above. The rare carded example of the set shown below is shared courtesy of Greg Marsho. It may be one of the most disturbing GI Joe images, as our hero appears to be preparing for an assassination.
