A large number of badges were produced during the war that allowed people to show they were doing their bit when wearing civvies. Within some local authorities specific badges were made to convey a position within the ARP warden service. The below badge is a fine example for a City of Birmingham Divisional Warden. There are hundreds, if not thousands, of home front lapel badges from the war and they are avidly collected today. Prices can range from a few pounds to several hundred.
