What a collection. That's too many postcards, here in Venezuela it is not usual to receive letters by mail directly. Yes, there are authorized postal agencies and all that, but receiving them at home, I think it's unlikely. I have never seen it. I loved the postcards from Germany. In the case of parcels, that does come.
Surprising that you have postcards from Canada and Taiwan. It's a universe that collection. 😍
Oh, so it is not common to receive letters at home address? But when you want to send a letter or postcard, there is a need for postage stamps, right?
Thank you, I am glad I was collecting these stamps over many years
