In the 1980s I had a collection of envelopes from all over the world. In April 2017 I started again with a new collection. My aim: an envelope from every stamp issuing authority in the world, including local posts. Also envelopes with permanent pictorial postmarks and special means of sending mail.
This collection and this blog will grow during the coming months and years. Comments and suggestions for links or (local) postal administrations are welcome.
