With Best Wishes for Christmas - 1921

This charming vintage Christmas greetings postcard picturing a sprig of mistletoe and holy beneath a message for a "blest Christmastide" was posted to a London (UK) address on 21 December, 1921.

It is edged with a decorative embossed border and has a serial number 1619-5, however other than that, I have no other clues to the manufacturer!

Happy Holidays!
