509th Radio Research Group Vietnam Photo Album. 94 photos, all color. Typical assortment of photos ( hooches, USO shows, misc aircraft, vehicles, etc. One great shot of the unit named painted on a truck bumper). In the front of the album are various documents and certificates all named to the same soldier. The documents, have been exposed to moisture at some point. You don't see ASA related photo albums that often. Neat piece.
