The correct spelling for the airfield is Marianna Airfield, later known as Graham airfield, named after one of the civil pilot instructors who worked there. Marianna is located in the panhandle of Florida, or as we refer to it LA (lower Alabama).
Beautiful job on the A-26 and the display. I'm sure the family will be pleased with the tribute.
A short diversion:
When I was in high school, living in Saratoga, Wyoming in the mid-60s, an A-26 landed at our local airport. It was owned by a couple who used it like a flying Winebago. They flew into an airport, rented a car to see the sights, and stayed in the aircraft at night. The mid-section of the fuselage was equiped with picture windows of plexi-glass. That was unique.
Years later, probably in the late 1980s, I was idling away some time in the Valiant Air Command hanger in Titusville, FL, when lo and behold what did I see, but that very same aircraft, sitting in the middle of the hanger with VAC decals. Just so you know where you can still see one.
