This photograph was taken in a nightclub in Mexico City on 22nd January, 1963. It is believed that the men in the photograph are all members of Operation 40. Closest to the camera on the left is Felix Rodriguez. Next to him is Porter Goss and Barry Seal. Tosh Plumlee is attempting to hide his face with his coat. Others in the pictureare Alberto 'Loco' Blanco (3rd right) and Jorgo Robreno (4th right).
P.S. The picture has only a tenuous connection to this post, being as it comes from a story about Barry Seal. It makes some interesting reading in its own right.
