I'm impressed this one arrived with only a 49c stamp on it!
Oooooo.... Maybe this explains the delay....?! It's taken a long time to arrive!!!!
Maybe... if there is a return address it would normally have been returned for postage due, or you would have had to pay it on your end. I think that quite often the machines just want to see a stamp, so it makes it through anyway on some occasions. Severe winter storms can also severely delay mail processing. And sometimes who knows why something is late.
A mysterious letter sent to the mysterious Eduardo which had a mysterious journey to get here! I love it! It's perfect!!! :-)
