Here is a lovely vintage postcard from about 1943-1945. When I can't see the postmark well or when I can't see at all, I always check the stamp. I have a stamp catalogue where I look up the issue of the actual stamp.
So the stamp of this card was issued in 1943 and it was used until 1945.
I love this charming Christmas scene.
You can find my other vintage Christmas postcard if you click on the label 'old Christmas cards' on the sidebar.
