This was the envelope that Snelly sent. At first I looked at the stamps and thought how nice and interesting they were and then I noticed that one was missing. Looking at the photo you can see in the corner. It had obviously been stamped by the Post Office and obviously it was lost after it left Russia.
Some questions came to mind.
What stamp was supposed to be on the envelope?
Did someone steal it? To add to a collection, maybe.
Is there a stamp fairy?
A Postal Mystery.
