PostNL announced on 25 March a special stamp featuring the smartest mammal in the Netherlands: the fox.
A unique aspect of these stamps is that after scanning with a smartphone a video of a mother with young foxes is shown. PostNL launches the stamps in collaboration with the Foundation for Nature Footage.
After the stamp issue of the squirrel earlier this year, now a stamp of the fox will be issued. Both stamps can be scanned with the Chameleon Explorer app on your smartphone. The app can be downloaded at
