With AAP I mean it is an 'Add to And Pass'. Number 014, but I've received many more. Just recently I started to give them a number, to organize and to get some overview. This one landed in my mailbox from Guatemala. In his invitation to add to and return, Clemens Luhmann suggested to cut this (A4 size) in two halves, keep one half and add to the other half to return to Guatemala. First I thought to cut it in two A5 size halves. But now that I am posting, and seeing a digital version, I think there are much more ways to cut a rectangle in two! And did I first saw two numbers '7' and two letters 'c', suddenly now they remind me of two... nostrils?!?
So, to be continued.
