Yes--this is a great photo! Thank you for posting it, Svetabel.
I've read two accounts of the last minutes of King Christian's life. In one story, Dagmar comes into his room and sees that he's looking very worn out. He tells her he isn't, and to proove it, he dances with her around the room. He stumbles, and a little while later he dies. In the other story (which I somehow believe to be more truthful) after dinner, Christian goes to his room, and when Dagmar comes in to check on him, she finds he has died peacefully, in his sleep.
