Royal Jigsaw Maps

From the Telegraph:

Kew Palace slotted an important piece of its royal history back into place yesterday when it unveiled a cabinet of jigsaw maps used to teach King George III's children.
The mahogany cabinet houses a collection of dissected maps – precursors of the jigsaw puzzle – and was a main feature in the nursery at Kew, the King's main home, in the mid-1700s.
It was through assembling the carved wooden pieces that a young George IV and William IV first learned the geography of Europe, the Empire, Africa and the American colonies they believed they would one day head.
