Thanks Doug. I was wondering why so many stamps and none from the US - then realized that, unlike the US, foreign Post Offices are also in charge of telecommunications.

Below is a link to my site, with several folders, including a folder of Teletypes in Movies and TV; and a folder of Teletype, Telecommunications and telegraphy related Postal (Postage) stamps, from all over the world.

You will see Teletype, Telex, Teleprinter, and telegraphy equipment.  Their are MANY depictions of punched paper tape, which is a very common theme in the designs.  Enjoy.  Additions welcome.
