Vintage Ninth Air Force & USAF Tactical Air Command Plaques From 3 Star General Estate. This came from an estate sale and had belonged to USAF Lieutenant General Marvin Leonard McNickle. The Large Plaques measure 18″ across and 18″ high. These may have hung in an office at one point. The back of the plaques have the name of the LT Colonel who probably these were given by. Plaques show lots of dust over from storage and some scuffs / scratches / dings / dents and marks over. Please see all 24 Pics.
