This represents an envelope labelled "Bypost" and containing this group of stamps. I am assuming, because some are identifiable as Swedish that they may all be but I do not know.
I do have a few questions for some knowledgeable person.
First, do these represent a number of private carriers operating in various cities and what market were they servicing that the Post Office did not handle?
Second, what time period do these issues represent?
Third, are they all from various Swedish cities or do some originate elsewhere, as Denmark or Norway?
