Here is the stamp on another envelope from Eva sent in 2017 that I really thought I had blogged, but I couldn't find it in the archive.
The interesting thing is that it is described as undeliverable, even though the address is correct and quite clear. You can also see someone must have put the yellow sticky paper on the envelope and then ran it through a machine, as the top part (including the word Nixie) is partly printed on the envelope.
Fortunately it made it back to Eva, who then sent it back to me.
Lucky for me, because I got to see all the fun mail creatures.
What was your craziest mail misadventure that turned out well in the end?
