and from 1946 (l) to the more sedate 1976-82 version (r)
so, when this stamp arrived in my mail this week, I assumed at first it to also be Dutch.
There is no date on this German stamp, but I believe it to be a 'supplemental 2 cent' stamp for use with older issue stamps when the price increased in 2015.
which is far easier to deal with than our 22¢ supplemental stamp!
