Does anybody know about in what years re-issues of the 1913 Zurich - Flugspende series have happened?
I've seen some with a 1993 year on the stamps and then I've seen some that I don't know when they were issued that don't have all the wording on the front of the stamp.
I've just got one left to complete the 1913 series but keep getting tripped up by auctions selling re-issues that I have to take a closer look at to be sure I'm getting the right one (as one should always do). Just curious about the history of these stamps though since someone appears to have continued to release them at later points of time.
Will post what I believe to be originals with this, then post what I think are re-issues after.
