The post card is from Rome, very close to the house were I was born. The church on the right (it's the building with 2 bell towers) is called "Cristo Re", I was baptized there!
Here's the translation:
Jan 26, 1941 - XIX
Dear Pierina - I wish and hope that you all are in good health. If you send me the address of your 2 children we will arrange a visit them and I will be able to tell you how they are doing, with precision. I recommend the house and the church. Greetings to all.
