Dead stock German green cotton Taschentücher handkerchiefs. The other stock these were with was all pre-war and these certainly look like they could be as well. However, this style was produced for decades, so it is hard to definitively date them. It measures 16" by 15 3/4"
Price is for one new old stock handkerchief. The color may vary slightly; they may be slightly more green than those pictured.
