NVA or Vietnam National Flag

NVA or Vietnam National Flag- Unsure of the vintage on this flag but was purchased from an old collection.It has a red bunting material with a separately applied yellow star. The star pattern was cut out of the red field then the star was applied. There looks to be a very small remnant of a tag on hoist end. The hoist end is folded over to accommodate a pole or dowel for hanging. It measures 30' (76cm) x 20' (51cm).It is in very good condition!
