Aircraft Warning Service Army Signals Sweetheart Hankie Portland

Vintage WWII AWS (Aircraft Warning Service) sweetheart hankie. Great graphics with airplanes and signal flags. I am not sure what all of the text exactly means. Portland Red 42J 1944. Army Go Ahead. Check Thank You. A.M. 0600 1200. Good condition overall. There are a few tiny specks by the planes in the center and one tiny hole in the AWS wing by the "Army Go Ahead" text. I've never seen another sweetheart piece like this.
