I’m bringing up an old thread here- I hope this is ok, it seems to be the best fit since my question concerns markings on the writing side of the card.
Yesterday I bought a few touristy postcards of my city. On the back they have the barcode, which is no problem since it is in a convenient place and will be covered by the stamp anyways.
But they also have a line across the writing side of the card, which is marked “do not write below this line”.
I haven’t noticed anything like this before on postcards, and I’ve never heard that you should leave part of the card empty. Has anybody an idea what the thought behind this is? Are there countries where the postal services need this space for special markings, and it could possibly happen that cards can’t be forwarded properly without it?
What would you do? Leave it empty as intended? Put some tape or stickers over it to make it look a bit nicer? I think just writing over/past the line would not look too appealing, and also I don’t want to be the person that writes past the line that says “do not write below this line”, if there is a reason behind it
