Vintage WWII American Red Cross volunteer nurse aide pin. Marked MA on the back. Fairly good condition with some wear.
The Volunteer Nurse aide pin could be fastened at the center front of the jumper at the neckline. This uniform was allowed to be worn after the first 34 hours of the Nurses' Aides course (which lasted a total time of 80 hours) had been completed. The uniform looks like this.
