This is quite a rare daybadge, that is unknown to many (most?) collectors of NSB collaboration memorabilia: the official badge (tinnie) that was handed out on occasion of the Nine Year Eistence of the NSB in 1940. See the enclosed picture with two such badges in wear.
The badge consists of a metallic pin on which is affixed on top a double sided paper label, that shows on both sides the red and black colors of the NSB, with in the centre a small triangle with the letters “NSB”.
We found a small lot of these badges, and they are or course 100% original!
All are in good condition and very rare to find. Since many collectors dont know these badges, they are missing from many collections. I’ve heard collectors call them “cheese-flags”, but they are official daybadges that were as decribed above here worn on occassion of the nine years existence of the NSB in 1940!
The price is naturally per piece.
