Neat - and actually not that easily found! - colourful, Dutch Waffen-SS volunteer-related propaganda- ie. collaboration-related 'sticker' ie. stamp entitled: 'Landgenooten steunt de Nederlandsche Ambulance in het Oosten'

I recently found four - fully identical and actually not that easily found! - examples of the colourful, Dutch Waffen-SS volunteer-related propaganda- ie. collaboration-related 'sticker' ie. stamp entitled: 'Landgenooten steunt de Nederlandsche Ambulance in het Oosten' and that come all four in an overall very nice- (ie. simply never used- ie. 'virtually mint', condition. These paper-based 'stickers' ie. stamps were used to (for example) glue onto letters and expressed sympathy for the various Dutch volunteers serving at the Eastern Front. The neat pieces (of which also posters exist with the same design) show an illustration of a Red Cross ambulance-car and mention the bank-account (ie. 'Giro 87600') and abovementioned text. The pieces are sized 7,2 x 5,2 cms. and retain a fully preserved glue-based 'backing' (as can be noticed on the pictures). My asking-price is naturally intended for a single example. Simply a neat occasion to acquire a Dutch, Waffen-SS volunteer-related propaganda- ie. collaboration-related 'sticker' ie. stamp for a justified price!
