It’s not the first time historical images of Kate have sent fans into raptures.
Images of the Duchess holding Prince George as she left the Lindo Wing in London shortly after William and Kate presented George to the public, in front of many members of the press after his birth prompted many comments.
One wrote: “Eight years ago the Duke and Duchess of Cambridge introduced their first child, a son and future King, to the world.
“Imagine having to face this just hours after giving birth?
“The composure and class this couple, particularly Catherine, showed and continues to show is amazing.”
