It is a very typical Dutch city bike (Lala
has a few of these). The womens
variety is known as Omafiets (grandmothers bike?)
Your design can be anywhere from the mid 1930's up to
modern produced yesterday, these bikes have not changed
very much in the last 70 years!
I am not familiar with the Super brand. I know of
Superia. I can't quite make out what it says on the
decal besides Super and Netherlands, I believe there
is a city name?
Any other Identifying marks would be quite helpful.
thanks,
Marty
