'Kreistreffen in Minden' 1937 Tinnie

'Kreistreffen in Minden' 1937 Tinnie (Veranstaltungsabzeichen), this gathering was held on 3-4 April 1937 in Minden. The tinnie has a pin-back device to its hollow-back reverse. The tinnie is not visible maker marked. The tinnie is very lightweight, stamped from a thin metal sheet. Nice original early tinnie!
