This hand size Stonehenge Diorama was made in China in 2002 for a Japanese toy company Medicom Toy Corporation as part of "The Great Mystery Museum Collection" a collection of 12 toys including this one of Stonehenge. I think it was designed by Yukitoshi Murata with a connection to TimeHouse.
This tiny about 7mm high, 75mm long, and 62mm wide model came packaged with a Stonehenge Collectors Card.

Although this little diorama has lost the distinction of being the smallest to Silver Stonehenge Charm this hand size example is by far, more detailed and accurate than the charm.
