The Inverted Jenny Postage Stamp
In 1918 the post office printed the first airmail stamp. The printer made a mistake, as you can see, the plane is upside-down. The "error" stamp became very rare and is now worth over $1.3 million dollars!

This Simmons World Dinosaur Stamp has an error too. If you can find the error, have a grown-up send your answer below. If you get it right you win a prize and a membership card to Simmons World. Good luck!
