When I received the postcard from David, I remembered that I also had this postcard of England! It shows Buckingham Palace from St. Jame's Park. On the right you can see the Queen Victoria Memorial.
The card was sent on 14 December 1948 from Kostas to Alice. He writes: "Dear Alice, thanks a lot for your letter and your wishes, I also wish you Merry Christmas and a Happy New Year for your baby girl. I salute you, Kostas"
