John Carter Decoder Badge
I’ve created a printable decoder badge based on the Thern medallion that transports John Carter to Mars/Barsoom in the movie. At the top of the badge you’ll see the Barsoomian(?) characters used throughout the official John Carter merchandise (such as the soundtrack booklet and activity books) while at the bottom you will see the English equivalent character.
The badge requires a paper fastener to spin.
You can download it here.
