Winterhulp Nederland (WHN) Collecting Tin.
On the bottom is the unique issuenumber of the tin #31415
It has been sandblasted and repainted at some point.
The typical WHN cloverleaf is impressed in the basemetal, so it is not just white painted on, but also actually in the tin. These variation with the actual cloverleaf are much more desirable than the ones without.
A great displayitem that belongs in every Dutch World War 2 collection!
