Quite often we receive mail that is addressed to tenants who previously lived in our house. A lot of it is junk and the previous tenants have left on a round-the-world-tour so we have nor forwarding address.

Because I am a snoopy bastard I opened one of the letters because it looked interesting and had a certain weight to it. It was addressed to a previous tenant and was sent from Malta.

What was inside was definitely not a normal letter. As you can see from the pictures it seems to be some sort of a transponder manufactured for IBM by a company called Lyngsoe Industries called Postag. I can’t seem to find any information on Postag anywhere on the Internet. The letter also came with a piece of paper asking the recepient to mark when they received it and send the letter back. So being the responsible person I am, I took two photos and left it on my mantle piece.

Tin-foil hats anyone? :)
