In the Christofle catalog from 2000, we find three of the four models: The fan is named "certainly", the moon and the globe are named "Eternellement". I don't have the name of the heart.
No piece is hallmarked.
They are in preformed Chritian Lacroix boxes with the booklet.
Under the boxes, it says "This item can only be sold by resellers approved by Christofle".
One of the boxes is damaged.
