Happy belated birthday to Margrethe....

Happy belated birthday to Margrethe II, Queen of Denmark (b. 16 April 1940). Her arms are as follows.

Overall an escutcheon Or two bars Gules (for Oldenburg)

Motto Latin: Magnanimi Pretium

The achievement is crowned with the Crown of King Christian V and mantled gules lined Ermine. Around the shield are the collars of the Order of the Dannebrog, and Order of the Elephant

You probably noticed that things got a little complicated in the 3rd quarter. I'm not sure why they haven't leveraged the redundant 4th quarter or used a simpler blazon. I suppose that devoting an entire quarter to something that looks a bit like the arms of Sweden has something to do with it.
