UNESCO Postcards.

Today, I received a lovely decorated envelope from the US with used stamps on paper in it. It has no note. It can come from a member of any of these clubs. So, whoever sent it: Thank you very much! You have made my day, Jessica

Hi Danubius,
Nothing! No ID and no name. And nobody replied to any of my messages. Still, it is a lovely surprise!
Have a great day, Jessica

Hi, I can't identify an ID for you. If there is a name on the envelope, I can search for a member.
