Good morning, Bimba:
I apologize for bothering you. I sent you postcard ES-421 in April, and it's still unregistered. It will be automatically canceled by Europa Stamps Postcards in four days. Have you received it? If so, please register it. Thank you in advance. I have several postcards I sent to Russia that haven't arrived yet and are about to expire.
Best regards, Fernando (Tenefe)
