This envelope was mailed by my friend Lluïsa in Madrid (Spain) on 11 September 2017, or so the postmark indicates. It arrived in Morocco on 19 October. Five weeks seem quite a lot for a letter from Spain...
The fact is that, if you look closely, you can see two postmarks. The round with the wavy lines is one of the commonest of Correos (the Spanish Postal Service). On the left, a second one, made on 3 October (exactly at 15h 56). So?
Maybe I am wrong, but I think that SWLF on the postmark stands for Sydney West Letter Facility.
So... the letter made, let's say, a little detour. Some letters just want to see a bit of the world.
