Forgive my ignorance regarding this topic,?
Then you will have to forgive mine too.
I have also puzzled about this. When airmail first became available there was a proliferation of airmail stamps and overprints, but they seem to have been used interchangeably with regular stamps.
As long as the postage was correct, the article was carried in the mail, whatever the type of stamp.
I can only assume they were produced as an advertising method to promote awareness of airmail services. But I could be wrong. It would be interesting to hear from someone who knows for certain.
Why would someone buy airmail stamps to send a letter from Budapest to Gyor which is within a couple hours drive, for example ?
Strange coincidence. I know a family from GyĂ¶r. They adopted the name GyĂ¶ri when they came to Australia because their Hungarian name was unpronounceable to us.
