CoffeCup, you might be right!!! I had not even thought about WHERE he had written the EVOL; but, now that I look at it after reading your comment, maybe he did do that so Nana would know if someone had opened the letter first!

Some of them he even sent Registered or Insured, so that someone would have to sign for them. This was during the winter months when she was staying at a "resort."
