For bid is an original October 1967 issue of "THE YALE SEA DOG" publication for alumni of the Yale University Navy ROTC (Reserve Officers Training Corps).  This was volume XII, issue number 1 of the ongoing publication.  Four pages of articles and photographs from the Vietnam War era.  Military history.  Sent to a Naval officer who was a graduate of Yale University and who was a member of the Yale Navy ROTC organization back in the 1930's (he was a June 1940 graduate).  

Issue was folded to fit in a mailing envelope.  Excellent, used condition. 

Interesting history.  Probably published somewhere in New Haven, Connecticut.
