Rare 1st Army/1st Gas Regiment patch. French-made embroidered black 1st Army "A" on OD felt with 1st Gas Regiment blue and yellow shield between the legs of the "A". Unfortunately a considerable amount of the black thread of the "A" has deteriorated with age but the 1st Gas shield has remained nicely intact. Approximately 60% of the black thread remains. Measures about 2 9/16 x 3 11/16". Fourteen-day inspection/return privileges. Insured/signature postage will be $5.00. Thanks.
