Taken in 1971 while I was a helo pilot in Vietnam.  I worked it a bit, but those are scout aircraft of B Troop 7/1 Cav (commonly known as "Loaches" i.e. Light Observation Helos), of which I was a Trooper, I'm standing next to the airplane I flew that day (that's a blade jutting out there).  Custom framed and matted, under non-glare plexi.  If you're a vet there is relevance, if not it's history...and beautiful besides!
